Description
This needle roller bearing carries radial loads in a single row of rollers guided by a standard cage, built to DIN 617/ISO 1206. Outside diameter is 85.0 mm, width 25.0 mm, and net mass 0.272 kg. The limiting speed reaches 6700.0 1/min, with a reference speed of 3850.0 1/min. The bearing has no seal, so shaft-side sealing and grease or oil supply must be arranged separately in the housing. The full-complement roller set gives high radial load capacity for its cross-section, and the design without an inner ring requires a hardened and ground shaft seat matching the specified bore geometry. The standard cage keeps the rollers evenly spaced, supporting stable running up to the stated reference speed under correct lubrication.
