Product Details
The Bearings Limited J188 OH needle bearing is a drawn cup, caged design featuring an oil hole and a bore size of 28.575 mm. This type of needle roller bearing falls into the category of roller bearings, which can be classified as radial or thrust based on the load direction they support. The needle roller bearings are designed to incorporate rollers that slightly exceed the size range of traditional needle rollers as specified by ISO, and they come in two variations: caged and full complement. Constructed from carefully selected alloy steel sheet, the drawn cup outer rings undergo surface hardening following a precise pressing process, resulting in a unique structural integrity. The cage is engineered to accurately guide the rollers at the pitch diameter, while its hardened surface minimizes frictional torque and enhances both rigidity and wear resistance.
