Insert bearing is a variant of the deep groove ball bearing. They are most commonly produced with a spherical OD to allow for misalignment, but are also available with a cylindrical OD. Insert bearings are specifically designed for mounting on shafts without the need for adapter sleeves, lock nuts or shoulders. The bearing is locked in place by set screws or a locking collar. The inner ring usually extends on one or both sides of the bearing to provide additional shaft support. Insert bearings are used to withstand radial and axial combined loads, which are mainly radial ones. Generally, it is not suitable to bear axial loads alone. Due to their versatility, they are popular in many applications. Industries using these bearings include conveyors, food and beverage processing, and packaging machinery, etc. These bearings usually come pre-lubricated with a multipurpose lithium-based grease and allow for re-lubrication. Insert bearings are also available in free spinning design and a black oxide finish upon request. We can provide customers with normal insert bearings, including metric and inch specifications, and offer one-stop sales services.
