Bearings are one of the important parts used on motorcycles. Although there are differences according to different models and structures, each motorcycle is generally equipped with 20 to 30 bearings. These bearings are used to support important rotating parts such as engines, transmissions, wheels, etc., and are responsible for reducing friction and promoting the transmission of engine power to the wheels. Bearings for motorcycle engines and transmissions are required to be used under conditions of high temperature, high-speed rotation and large impact loads, therefore, the bearing is required to have foreign body resistance and high rigidity. Wheel bearings must be suitable for various terrains and uses of vehicles, so they must be durable against water and mud. The performance required for motorcycle bearings is to achieve smooth rotation with low friction and low vibration, and to ensure durability. These properties affect the fuel consumption and safety closely related to our lives. ZYS always pays attention to these details, improves people's quality of life and protects the earth's environment, and strives to carry out related development and best design work.http://www.zysbearing.com/deep-groove-ball-bearing/deep-groove-ball-bearings.html View Details
Full interpretation of the causes of vacuum pump bearing heating
Full interpretation of the causes of vacuum pump bearing heating1.

Cracked valveWhen a valve is cracked, the pressure excitation on both sides of the impeller will be unbalanced, and the axial force will occur on the rotor, which will increase the bearing load and cause long-term operation.The bearing temperature rises. In this case, the valve disc should be replaced in time.2. The shaft end seal failsWhen the shaft end sealing packing is damaged or the sealing water hole is blocked, Caicheng air is sucked into the pump body from these damaged gaps and will formThe suction and exhaust performance of the pump. Weaving-When the side seal fails, the pressure on both sides of the impeller will be unbalanced, and the rotor will have an axial force that will cause the bearingThe load increases, which increases the bearing temperature.3. The bearing preload is too largeThis situation will promote bearing clearance reduction or no clearance, resulting in bearing heating.4. Sensational impactWhen the sensation of the slurry or the bearing is large, the appearance of the bearing temperature will be too high. Look at the pump body to find out the cause of the sensation. To eliminate the sensation, the bearingTemperature rehabilitation5. Smooth appearanceIf the increase amount of the lubricating grease is too large or too small, or the type of the lubricating grease does not meet, the use time is too long or the lubricating grease will be contaminated, which will cause bearing heating.At this moment, you should check the type of lubricating grease, ask the manufacturer for the appropriate dosage, and adjust the lubricating grease to recover the bearing temperature.
