Four-point contact ball bearing is a single-row angular contact ball bearing with separate inner and outer rings. The inner ring is divided into two parts, and one bearing can bear axial loads in two directions. The contact angle is 35°, and the axial load capacity is large, which is suitable for bearing pure axial load or synthetic load with large axial load.Four-point contact ball bearings are interchangeable with face-to-face or back-to-back angular contact ball bearings.Four-point contact ball bearings use copper alloy machined cages.

More >>The main chemical components of bearing steel are carbon, chromium, silicon, manganese, nickel, molybdenum, vanadium and so on.I. Carbon effectsExcept carburized steel, the carbon content of bearing steel is 0.95-1.15%, which belongs to hypereutectoid composition. Thus, high hardness, high contact fatigue strength and wear resistance can be obtained after quenching and tempering at low temperature. In order to form enough carbides to increase the wear resistance, the carbon content should not be too low, but too high carbon content will increase the non-uniformity of the carbides and make the mechanical properties of the carbides decrease with the formation of reticular carbides.II. Effect of alloy elementsChromium is the main chemical component of bearing steel. Chromium can improve hardenability, reduce overheating tendency and improve low-temperature tempering stability. Silicon and manganese in bearing steel mainly improve hardenability. Nickel in Carburized bearing steel can improve the toughness and plasticity of steel. Nickel can improve the fatigue resistance of steel and reduce the sensitivity of steel to notch. Molybdenum in steel can improve hardenability and thermal strength, prevent tempering brittleness and increase corrosion resistance in certain medium. Vanadium increases the strength and yield ratio, especially the ratio limit and elastic limit, and reduces the decarburization sensitivity during heat treatment. Thus the surface quality of bearing steel without chromium and vanadium is improved.

More >>Bearing clearance is the clearance (or interference) inside a single bearing or a system composed of several bearings. The clearance can be divided into axial clearance and radial clearance, which depends on the bearing type and measurement method.Why should the bearing clearance be adjusted?If the bearing clearance is too large or too small, the working life of the bearing and even the stability of the entire equipment operation will be reduced.The method of clearance adjustment is determined by the bearing type, which can generally be divided into non-adjustable clearance bearings and adjustable bearings.The non-adjustable clearance bearing means that the clearance of the bearing is determined after the bearing leaves the factory. The well-known deep groove ball bearings, self-aligning bearings, and cylindrical bearings all belong to this category. Adjustable clearance bearing means that the relative axial position of the bearing raceway can be moved to obtain the required clearance. In this category, there are tapered bearings, angular contact ball bearings and thrust bearings.For non-adjustable bearing clearance, the industry has corresponding standard values (CN, C3, C4, etc.), and specific clearance ranges can also be customized.The choice of the best working clearance is determined by the application conditions (load, speed, design parameters) and expected working conditions (maximum life, best stiffness, low heat generation, ease of maintenance, etc.).

More >>From January to March, domestic crude steel production of bearing steel increased by 23.97% year-on-year, and the output of bearing steel increased by 17.08% year-on-year. Looking back at the bearing steel market in April, the domestic bearing steel market prices continued to rise, driven by the rising cost of steel mills and the strengthening of the futures market in late April. Up to now, the average price of domestic bearing round steel 50mm (continuous casting) is 6255 yuan/ton, an increase of 155 yuan/ton from the end of March, an increase of 2.54% month-on-month. At present, downstream procurement costs have increased significantly compared with previous years. Excessive capital pressure has led to a slight slowdown in downstream procurement efforts, and the overall acceptance of high levels by terminal enterprises is low. With the announcement of the cancellation of export tax rebates for steel products, enterprises are more concerned about the subsequent impact on the export of bearing steel. However, in the recent stage, under the background of good fundamentals and high demand, under the stimulus of the continuous increase in the price of high-quality steel, it is expected that the market price of bearing steel in May may continue to rise.

More >>In May 2020, the first ISO standardization document ISO/TR 20051:2020 in the field of rolling bearings developed by China-\"Derivation of Rated Load Coefficient of Joint Bearings\" was officially released. This document is the first time that China has taken the lead, and led by Luoyang Bearing Research Institute Co., Ltd. with the participation of Fujian Longxi and Huangshan Colleges. Its release has achieved a zero breakthrough in the field of international standardization of rolling bearings in China.The ISO/TR 20051 project was established in May 2015. After the 4th edition of the WD draft and multiple CD draft revisions, it was finally successfully released and constituted a key supplement to another international standard ISO 20015:2017 \"Calculation of the rated dynamic and static load of Joint Bearings\". ISO 20015 gives the engineering calculation method for the rated dynamic and static load of joint bearings, but does not give the core content-the derivation method and recommended value of the rated load factor, that is, the theoretical basis, Mathematical model, derivation process and numerical results for determining the coefficient in each calculation formula. ISO/TR 20051 provides background information for this part of the content, which is an important supplement to ISO 20015, and forms a complete standard system together with ISO 20015. When countries have unified the rated load factors of joint bearings, the rated load values of joint bearings can be unified, so that users of joint bearings can use the same standard to measure the quality of bearings and help bearing manufacturers improve their quality.The successful release of ISO/TR 20051 marks the further improvement of China\'s influence and right to speak in the field of rolling bearing international standardization, and will also accumulate valuable experience for my country to undertake other rolling bearing international standard formulation projects in the future.

More >>ZYS Hybrid Ceramic Ball Bearing Line Ideal for Electrical Machinery and General Industry Applications - Excellent electric insulation properties with high-speed and temperature capabilities Plymouth, MI… ZYS Americas, the North American subsidiary of The ZYS Group, China’s largest bearing producer, and one of the world’s top 10 bearing manufacturers offers a wide range of hybrid ceramic ball bearings for electrical machinery and general industry applications. ZYS hybrid ceramic ball bearings are engineered to maximize the benefits of precision steel ring construction and lightweight ceramic balls. In addition to delivering excellent electric insulation properties, they provide a higher-speed and higher temperature capability and longer service life than all-steel bearings in most applications. The bearings are available in a variety of configurations with bores from 17 – 90 mm, ODs from 40 – 190 mm, and speed ratings as high as 21,600 RPM/min. Better high-speed, high temp capability ZYS hybrid ceramic bearings are constructed of steel rings and silicon nitride (Si3N4) balls, which are approximately 40% of the density of steel. This gives the bearings a lower inertia and better high-speed capability than standard bearings. The lower inertia results in less loading on the raceway and provides superior performance during rapid acceleration and deceleration. The silicon nitride balls also have a lower coefficient of friction so they generate less heat at high speed, greatly improving the life of the grease and the bearing. As a result, the bearings are less sensitive to temperature changes and high temperature operating conditions that can affect both running accuracy and internal clearance. Less wear and false brinelling The silicon nitride used in ZYS hybrid ceramic bearings is much harder than steel, which improves the overall stiffness of the bearings and makes them resistant to damage from contamination. ZYS hybrid ceramic bearings are also less susceptible to false brinells. When a stationary bearing is subjected to external vibration, the metal-to-metal contact between the balls and raceways can result in abrasions known as false brinells. The wear particles created by false brinells can contaminate and breakdown the lubricant, causing increased noise and vibration. Excellent electrical insulation ZYS hybrid ceramic bearings are ideal for use in electric motors and generators that are prone to stray electric currents. The bearing design insulates the inner ring and the outer ring of the bearing, effectively preventing the flow of stray currents. This helps to avoid arc-pits and secondary damage that can result in increased noise and vibration, heat generation, lubricant breakdown, and premature failure of the bearing. Replaces both hybrid ceramic and conventional bearings ZYS hybrid ceramic bearings can be used as direct replacements for existing hybrid ceramic bearings as well as conventional bearings in all applications. They are lubricated for life with Mobil Polyrex EM grease and sealed with low-torque, non-contact seals (-2RZ) to ensure optimum efficiency for torque-sensitive applications and adequate protection from contamination. Handling and mounting are identical to steel bearings, so standard installation tools and methods can be used. ZYS Americas offers a full line of bearing types and styles for use in original equipment manufacturing, aftermarket replacement, and MRO operations. The ZYS portfolio includes over 30,000 types of bearings in a wide range of specifications and sizes ranging from 1.5mm ID to 4000mm OD. As China’s largest bearing producer, and one of the world’s top 10 bearing manufacturers, ZYS utilizes the formidable production capabilities of its nine manufacturing centers, 34 bearing plants, and 22 vertically integrated component plants to produce over 2.8 million bearings per day. ZYS relies on state-of-the-art manufacturing and stringent QC in order to maintain its leadership position in the bearing market.

ZYS dental drill bearing can give a stable performance as 400 thousand revolutions per minZYS (RPM), which has led dental treatment to a painless era.S418 and S718 series dental drill bearing, the ferrule and balls are made of 440C stainless steel. ZYS also makes silicon nitride ceramic ones according to customer request. Currently, we are using stainless steel balls from Japan and Si3N4 silicon nitride ceramic balls from Saint-Gobain (USA).We use super resin material with titanium fibers to make ZYS’s self-developed S418 series dental drilling bearing support frame. Since the hardness of titanium fiber is much lower than fiber glass, it protects the counterpart from friction. We also added some portion of solid lubrication in this resin to reduce friction and let the bearing endure longer friction under high speed rolling. The lubrication capability of this material is quite suitable for dental drilling bearings to take high temperature and high pressure steam sanitization time after time, even in oilless condition. Because of the low friction of ZYS dental drilling bearings, it consumes less power but produces strong output performance. It also saves time and man power, preferred by many dental experts.

More >>ZYS Lubricant-free Bearings will Protect Environment The Iglidur plain bearings from Igus are tribologically optimised to ensure that no lubrication is ever required. Over 40% of all lubricants are ultimately released into the environment, seeping into water or soil, or evaporating into the atmosphere. A study by a research team of chemists, mechanical engineers and environmentalists at the RWTH University in Aachen, Germany, found that Germany alone consumes 250,000 tonnes of lubricants each year. To put this into perspective, this would fill 8000 standard tanker lorries. Most countries have a threshold level permissible in waste streams and hundreds of millions of pounds are spent annually treating aste water to get to acceptable levels. The Iglidur plain bearings from Igus are tribologically optimised to ensure that no lubrication is ever required. These bearings run without any oil or grease, so no contaminants escape into the environment. More and more applications which traditionally use lubricated metal plain bushes can now benefit from environmentally friendly plastic Iglidur bearings. While 15 litres of oil are required to produce 1 litre of aluminium and 11 litres of oil to make 1 litre of steel, only 1.8 litres of oil are necessary to produce 1 litre of plastic. In fact, only 4% of the world's oil production is used in the manufacture of plastics and this value is likely to decrease with the progress that is being made in the organic production of polymers. The first steps are being made in extracting carbon dioxide from power station emissions and using this to produce polymers such as polycarbonate and polyurethane. As well as the "no lubrication" environmental benefit of Iglidur bearings, there is also the issue of weight reduction. The light weight bearings help to reduce the fuel consumption and carbon dioxide output of vehicles, aircraft and plant machinery. The reduced weight leads to a lower required drive force and subsequently lower energy consumption. Iglidur polymer plain bearings have, as standard, high chemical resistance, whereas metal plain bearings often have to be coated to achieve this. The coating methods used include zinc plating, treatment and galvanising, consuming more energy. Iglidur plain polymer bearings are designed to be dimensionally interchangeable with lubricated plain metal bearings.
