Application of bearings
Wheel bearings can withstand a large axial load, radial load and overturning moment, such as integrated load durability tester sets, large bearings rotate, transmission, fixed and other functions in a special structure. Under normal circumstances, all with their own turntable bearing mounting holes, lubricants and seals, to meet the different needs of a variety of different conditions of work under the conditions of the various types of hosts; on the other hand, wheel bearings itself with a compact, rotating guide convenient, easy to install and easy to maintain, etc., are widely used in material handling equipment, mining machines, construction machinery, port machinery, wind energy, medical equipment, radar and missile launchers and other large rotary device.
Precision bearings according to ISO grading standards are divided into: P0, P6, P5, P4, P2. Rank higher in turn, where P0 is the general accuracy, other grades are precision level. Of course, different classification standards, different types of bearings, their classification method somewhat different, but the meaning is to the. The use of performance requirements of precision bearings rotating body with high runout accuracy, high-speed rotation and small changes in friction and friction.
