FAQS

QWhat are the types of roller bearings?

AThere are a wide range of roller bearings, each with different designs used in varying applications. Cylindrical, spherical, tapered, and needle are the four primary types of roller bearings. Cylindrical roller bearings handle high radial loads and low thrust loads at high speeds. They also accommodate fast acceleration.

QWhat is the main purpose of bearings?

AThe main purpose of bearings is to transfer the vertical loads coming on to the superstructure to the substructure . Bearings facilitate movement caused by expansion and contractions.

QWhat are the function of bearings?

AFunction Of Bearings. Bridge bearings are used to transfer forces from the superstructure to the substructure , allowing the following types of movements of the superstructure: Translation movements; are displacements in vertical and horizontal directions due to in-plane or out-of-plane forces like wind and self weight.

QWhat is a rolling bearing?

AA rolling-element bearing, also known as a rolling bearing, is a bearing which carries a load by placing rolling elements (such as balls or rollers) between two bearing rings called races. The relative motion of the races causes the rolling elements to roll with very little rolling resistance and with little sliding.
