Machined Ring Needle Roller Bearing

Machined Ring Needle Roller Bearing mainly includes machined components, an outer ring and inner ring, needle rollers and a cage that guides the rollers. In this bearing, the cage or needle rollers are guided by the rib or side plate of the outer ring. Consequently, the roller and cage assembly cannot be separated from the outer ring. This product is best-suited to a space-saving design due to its low section height, and large load capacity. Another advantage is high rigidity and high bearing accuracy due to the machined outer ring. The outer ring has a lubrication hole and lubrication groove. Both single-row and double-row types are available.
