Thrust Ball Bearing Stainless Steel Automotive

Thrust ball bearings consist of two precision washers (rings) and a ball complement spaced by retainer. They can besupplied with or without radius ball grooves in the rings. Thrust ball bearings are used under purely axial loads, and its speed is limited.

There are two key thrust ball bearing assembly.A cage and steel ball bonding quality control, the other is a nominal highly T control after bearing assembly.In addition, due to the shaft ring and seat are separable, bring a management problem.Conventional is to prevent imported bearing parts.M type punching cage use flanging die assembly.After pressing demands steel ball in the pocket hole flexible rotation, but can not fall off from the pocket hole, and technical discipline inspection steel ball in the hole in the pocket up momentum.Entities cage stamping pressure too deep will make small steel ball up momentum, and bumps on the stamping connection with cage too little and strength is insufficient, prone to falling phenomenon, cause maintains a scrap.Small thrust ball bearing race and shaft circle diameter is slightly different, two sets of group there was no significant difference.To prevent mixing of phenomenon, namely pretended to be a set of bearing found two or are shaft is a circle.This needs to take certain measures.Or set of assistive tools will usually smoke ring, distinguish, or before sampling nominal height with inner diameter gauge inspection, in order to check the inner diameter is convenient, put under the seat, shaft ring above.If seat diameter have obvious quench heating oxidation color or not after grinding, it should not be necessary to test diameter, can clearly see the difference between the shaft ring and seat, not easy to mix.Thrust ball bearing assembly for nominal height after T measure, confirm whether qualified.Block or standard calibration, measured in height, and measured load, bearing rotating dozens of times, it is important to reach the minimum height.[1]
When the thrust ball bearings under the condition of high speed operation, steel ball and raceway radial plane of the contact Angle will be influenced by centrifugal force, causing steel ball relative sliding groove.This adhesive wear damage caused by sliding bearings.To prevent the damage, must ensure that the minimum load, thrust ball bearings are see formula formula 1 or 2, take calculated value of highly actie.
