Thrust (Axial) Ball Bearings

As a rule, one of the bear­ing wash­ers is pro­duced tight to fit on the shaft and the others are loose to be in­stalled in the hous­ing. Thrust (ax­i­al) ball bear­ings with flat loose wash­er do not al­low any, even slight, an­gu­lar misalign­ment be­tween the shaft and the hous­ing. If it is nec­es­sary to provide unit op­er­a­tion with ini­tial an­gu­lar misalign­ment, bear­ings with loose sphered seat wash­ers should be used. Usu­al­ly thrust (ax­i­al) ball bear­ings are pro­duced split, which sim­pli­fies their mount­ing, but for spe­cial ap­pli­ca­tions they can have stamped pro­tec­tive shield, which makes the whole con­struc­tion un­de­tach­able.

Thrust (ax­i­al) ball bear­ings are pro­duced with pressed steel cages, with ma­chined cages of brass, steel, alu­minum al­loys or glass fi­bre re­in­forced polyamide. If it is nec­es­sary to provide ex­treme­ly high ax­i­al load ca­pac­i­ty, the­se bear­ings can be man­u­fac­tured with­out cage with the max­i­mum num­ber of balls.
