Product Details
The Bearings Limited B138 OH needle bearing is a drawn cup, full complement needle roller bearing featuring an oil hole and a bore size of 20.65mm. As a type of roller bearing, it is classified based on the direction of the load it supports, either radial or thrust. Needle roller bearings consist of rollers that may slightly exceed the size range defined by ISO, and include variations such as drawn cup, solid radial bearings, and thrust needle bearings. This needle roller bearing is available in caged and full complement types, with its drawn cup outer rings constructed from carefully selected alloy steel sheet that is surface-hardened after precise pressing, which contributes to its unique structure. The bearing's cage accurately guides the rollers at the pitch diameter and is also hardened to minimize frictional torque while enhancing rigidity and wear resistance.
