The composition of the plane bearing of the automobile shock absorber

Planar bearings are also called pressure bearings, which are the most common type of McPherson suspension in automobiles, because the characteristic of MacPherson suspension is that the spring shock absorber exists as a load-bearing pillar, and this pillar is combined with the steering knuckle to bear the left and right rotation fulcrum of the steering . The plane bearing is placed on the top of the shock absorber, between the spring and the top glue of the shock absorber. It must bear the pressure up and down and can rotate freely, so it is an important part for MacPherson suspension
The automobile shock absorber plane bearing is composed of a row of steel balls (with a cage), a shaft ring (tightly fitted with the shaft) and a seat ring (tightly fitted with the bearing seat hole with a clearance from the shaft).
