Tapered Roller Bearings are designed to reduce friction and, in turn, reduce the heat that can cause bearing structures to fail. This bearing is used in many industrial applications and is optimal for those undergoing excess loads.
A roller bearing is a type of rolling-element bearing that uses a cylinder (roller) instead of a ball. In general, the cylindrical bearings allow for greater radial loads. They are made to handle heavier loads than ball bearings.
