NA4904 Budget Needle Roller Bearing with Inner Ring 20mm x 37mm x 13mm
Single row needle roller bearing with machined rings, with flanges.
Single row needle roller bearings incorporate cylindrical rollers that are small in diameter relative to their length. Owing to their large number of rollers, the bearings have a high load carrying capacity. The outer ring includes two integral flanges to guide the bearing axially and an annular groove with one or more lubrication holes to facilitate relubrication.
