When it is pressed into the shaft, only the small circle can be stressed, and the large circle can only be stressed. Prevention of lacquer rust: The characteristic of lacquer rust is that it mostly occurs in sealed motors. Its output accounts for more than 70% of the total output of bearings, which is the highest output, most commonly used and cheapest type of bearing in China.
The choice of grease: The choice of grease is generally based on the speed, temperature resistance, noise requirements and starting torque of the deep groove ball bearing. However, as a qualified salesperson, in addition to being proficient in product knowledge, he must also be proficient in the use of products, that is, clutch bearing manufacturers doctor-type sales, and choose the best supporting deep groove ball bearings according to the performance and use conditions of the user's supporting products.
This cage is guided by the ball like the stamping cage. When it only bears radial load, the contact angle is zero. If there is a tilt, the deep groove ball bearing channel will be damaged due to force, and the deep groove ball bearing will produce noise. In the past, many manufacturers thought it was the problem of deep groove ball bearings.01mm, and the interference during assembly is 0.
In theory, the noise and life of deep groove ball bearings reach the best state when there is zero clearance, but in actual operation, considering the temperature rise and other issues, the clearance of deep groove ball bearings after assembly is 0. This is the specialized manufacturing and sales popular among major companies in the world.
Contact seal has good dustproof performance but large starting torque, and non-connected seal has small starting torque but sealing performance No contact is good. , The business personnel must ask the operating conditions of deep groove ball bearings, the speed, temperature, and tolerance of deep groove ball bearings are directly related to the choice of deep groove ball bearing clearance.
