Insert Ball Bearings

Outer ring of in­sert ball bear­ings have spher­i­cal sur­face, which al­lows them to com­pen­sate some shaft misalign­ment when in­stalled in hous­ing with the same spher­i­cal hole. Be­sides the usu­al de­sign for in­ter­fer­ence fit, in­ner rings are avail­able in sev­er­al types, the main dif­fer­ence of which is in the ways of fix­a­tion on the shafts. The most pop­u­lar is the de­sign of in­ter­nal rings with lock­ing screws, with ec­cen­tric lock­ing col­lar or with the adapter sleeve. At the same time the de­sign of in­ter­nal rings with square or hexag­o­nal holes is al­so pos­si­ble. In­sert ball bear­ings are man­u­fac­tured with the most dif­fer­ent kinds of con­tact seals and rings coat­ing for re­li­able pro­tec­tion of bear­ing from the var­i­ous en­vi­ron­men­tal in­flu­ences.

In­sert ball bear­ings are usu­al­ly equipped with long-last­ing and durable cages of glass fi­bre re­in­forced or pressed steel cages for us­ing at high tem­per­a­tures.

Stan­dard­ized bear­ing hous­ings have a lot of de­signs and can be sup­plied in­clud­ing the bear­ings, or with­out them.
