Product Details
The Bearings Limited J57 OH needle bearing is a drawn cup, caged design with an oil hole and a bore of 7.95mm. As a type of roller bearing, it can be classified as either radial or thrust depending on the load direction it supports. This needle roller bearing falls under the category where the rollers slightly exceed the size range of needle rollers as per ISO standards. It includes drawn cup, solid radial bearings, and thrust needle bearings, available in two types: caged and full complement. The drawn cup outer rings are constructed from carefully selected alloy steel sheet, which are surface-hardened after precise pressing for enhanced structural integrity. The cage of the needle bearing is engineered to accurately guide the rollers at their pitch diameter and features a hardened surface to reduce frictional torque while increasing rigidity and wear resistance.
