Description

This needle roller bearing carries a solid outer ring with a machined bore for needle rollers guided by a standard cage, giving an outside diameter of 82.0 mm and a net mass of 237.9 g. The limiting speed reaches 6800 1/min, with a reference speed of 4500 1/min, reflecting the light XL series design intended for compact radial support. The cage-guided needle set keeps radial section height low while maintaining full rolling contact along the outer ring raceway, suiting applications where radial space is limited but load-carrying capacity per unit cross-section must remain high. The standard cage design allows relubrication with grease or oil according to the operating speed range, and the bearing requires a hardened and ground shaft surface acting as the inner raceway.
