FAQS

QWhat is an advantage of needle roller bearings?

AA main advantage of needle roller bearings is their ability to use mating surfaces as inner or outer raceways, or both. Bearing load ratings typically are based on raceway hardness of 58 Rc or equivalent. If it is lower, the capacity of the bearing-raceway combination is reduced.

QWhat is Mounted Units & Inserts ？

AMounted bearings, sometimes called bearing units or bearing blocks, have a bearing installed in a housing to ease installation and provide additional support for the bearing. They are face or surface mounted in applications where the shaft is perpendicular to the unit.

QWhat is Pillow Block Bearings ？

AA pillow block is a pedestal used to provide support for a rotating shaft with the help of compatible bearings & various accessories. Housing material for a pillow block is typically made of cast iron or cast steel.

QWhat is Precision Ball Bearings ？

AA precision bearing is anything that has a higher standard precision level (i.e. ISO P5 or ABEC 5). The step up from this is super-precision bearings that have a precision level of ISO P4 or ABEC 7 or better.
