The slewing bearing is a large bearing that can withstand comprehensive loads, and can simultaneously withstand large axial and radial loads and overturning moments. Slewing ring bearings are generally equipped with mounting holes, internal gears or external gears, lubricating oil holes and sealing devices, which can make the host design compact, easy to guide, and easy to maintain. Slewing ring bearings have four-point contact ball bearings without gears, external gears and internal gears, double-row angular contact ball bearings, crossed cylindrical roller bearings, crossed tapered roller bearings and three-row cylindrical roller composite bearings. Series, four-point contact ball bearings have higher static load capacity, crossed cylindrical rollers have higher dynamic load capacity, and the pre-interference of crossed tapered roller bearings enable the bearings to have greater support rigidity and rotation accuracy. The three-row cylindrical roller combined bearing leads to the height of the bearing due to the increase in load capacity, and various forces are borne by different raceways, so under the same force, the bearing diameter can be greatly reduced, so it has the characteristics of making the host more compact. A slewing bearing with high load capacity. Slewing bearings are widely used in large-scale slewing devices of cranes, mining machinery, construction machinery, port machinery, marine machinery, and high-precision radar machinery and missile launchers. At the same time, it can also design, develop and produce various special structure slewing bearings according to the specific requirements of users.http://www.zysbearing.com/slewing-bearings/ View Details
Ball screw bearing

Ball screw bearings have the characteristics of high precision, reversibility and high efficiency. This is a further extension and development of the trapezoidal screw. The important significance of this development is to turn the sliding action of the trapezoidal screw into a rolling action. Because of its low frictional resistance, ball screw bearings are widely used in various industrial equipment and precision instruments.In order to adapt to various purposes, ball screw bearings provide a wide range of standardized products. The circulation methods of the balls include circulating duct type, circulator type and end cap type. Preloading methods include positioning preloading (double nut method, position preloading method) and constant pressure preloading. The appropriate type can be selected according to the purpose. The screw has high-precision grinding precision ball screw (precision is divided into 7 grades from CO-C10) and cold-rolled ball screw bearing formed by high-precision cold rolling (precision is divided into 3 from C-C10) A level, only a few can do it). In addition, in order to cope with the urgent need for delivery by users, there are finished products that have been processed on the end of the shaft, semi-finished products and cold rolled ball screw bearings that can be freely processed on the end of the shaft. As peripheral parts of this bearing, the screw support unit, nut holder, lock nut, etc. necessary for use have also been standardized.Ball screw bearings are based on product technology accumulated over the years, from materials, thermal management, manufacturing, inspection to shipment, are managed by a strict quality assurance system, so they have high reliability.http://www.zysbearing.com/precision-bearings/ball-screw-support-bearings.html View Details
cold rolling machine
The cold rolling mill is a new type of steel bar cold rolling processing equipment. The machine can process hot-rolled wire rods and hot-rolled coils with a diameter between 6.5 mm and 12 mm into cold-rolled ribbed steel bars with a diameter of 5 mm to 12 mm. The cold-rolled ribbed steel bar rolled by the cold rolling mill is an updated product of ... The cold rolling mill is a new type of steel bar cold rolling processing equipment. The machine can process hot-rolled wire rods and hot-rolled coils with a diameter between 6.5 mm and 12 mm into cold-rolled ribbed steel bars with a diameter of 5 mm to 12 mm. The cold-rolled ribbed steel bar rolled by the cold rolling mill is an updated product of cold-drawn low-carbon steel wire in the prestressed concrete structure. In the cast-in-place concrete structure, it can be replaced with the grade I steel bar to save steel. It is a better kind of cold processed steel of the same kind. If speed adjustment is not required during the rolling process of the cold rolling mill, an AC motor can be used; if speed adjustment is required during the rolling process of the cold rolling mill, a DC motor can be used.The cold rolling mill uses a motor to drag the steel bars, and the load-bearing rolls and work rolls of the cold rolling mill are used to jointly apply force to the two surfaces of the steel bars. The purpose of rolling cold-rolled ribbed steel bars with different diameters is achieved by changing the size of the gap between the two rolls.① Load-bearing roller: The load-bearing roller of the cold rolling mill is the roller closest to the stand. This roller serves to hold the steel bar when producing ribbed steel bars, and equalizes the gravity of the steel bar and the work roll. Scattered on the load-bearing roller, so that the lower surface of the steel bar produces ribs.②Work roll: The work roll of the cold rolling mill is on top of the load-bearing roll and is the farthest away from the stand, so the roll mainly plays a role in rolling the steel bar lifted by the load-bearing roll when producing ribbed steel bars. , So that the upper surface of the steel bar has ribs.http://www.zysbearing.com/bearing-manufacturing-machines/precision-cold-rolling-machine.html View Details
An elevator in a community frequently makes strange noises

The sound of an elevator has been particularly loud recently, and it sounds like something is wrong with the machine. Standing in the elevator makes people feel uneasy. Yesterday, it was found that the elevator on the right side issued a "click" every time it went up and down. The loud noise makes people feel terrified.The person responsible for elevator maintenance introduced that the loud noise from the elevator was mainly due to the water in the elevator bottom tank, which caused the Elevator bearing to get wet, the butter dried out and rusted, and the bearing balls fell off. Prior to this, they had transferred accessories to the elevator production headquarters and had been repaired. However, at present, there are still cases where the doors are easily stuck.After learning the situation, the staff also went to the scene to check. After discovering that the elevator doors are still easily stuck, the staff immediately asked the maintenance company to suspend the use of the elevator. After the maintenance is completed, it must be inspected by the special inspection institute before it can be put into use. At the same time, the staff also required the use of excellent safety Elevator bearing to eliminate safety hazards. View Details
