Bearing belt you know bearing cage

Bearing cage, refers to the part of the package all or part of the rolling element, and with the movement of the bearing parts, used for protection, roller are correctly guide roller and keep it in the bearings. The key function 1 01 bearing cage. Make maintain moderate spacing between the rolling element, avoid to touch each other in order to reduce friction roller; 2. Ensures equal distribution of rolling body and make uniform load distribution; 3. In no load area correctly guide roller, to improve the rolling bearing, avoid the destructive nature of drag. Cage should assume due to friction, resilience and inertia moment of in-situ stress, also want to undertake in lubricants, lubricants, preservatives or chemicals due to the embrittlement, solvents, or chemical corrosion of cooling liquid etc. So the design of the cage and raw materials for its characteristics and bearing the credibility of the all is extremely important. 02 bearing cage type 1. Punching cage has the advantage of lighter weight, internal have a very large space, can be helpful for lubricant to enter; 2. Solid line maintains a generally allowed to have higher speed, when bearing in addition, there are other than the rotation movement way, very is high-speed cases, the application should also be machine cut metal cage. 3. Support cage to pin all of roller bearing with broken hole, will on both sides of the pin fixed on the ring. This kind of cage net weight is lighter, can accommodate a large number of roller, only to the giant roller bearings bearings. 03 bearing cage cage key raw materials of raw materials has a stamping, machine cutting steel, steel stamping, machine cutting brass, brass, etc. Stamping steel cage possess high compressive strength, can according to the metal surface treatment to reduce friction and damage; General to giant machine cutting steel cage bearing or unfavorable choose brass cage condition; Stamping brass cage to part of the big small and medium-sized bearings; Machine cutting brass cage generally are not subject to the bearing lubricant harm, and can generally clear lubricant, brass cage cannot be used in operating temperature above 250 ℃; The above is the content, the author has given you today to learn more about bearing small knowledge, pay attention to the bearing's official website.
