This needle roller bearing carries radial loads within a compact cross-section, using a full complement of needle rollers guided in a heavy-series design without an inner ring. Outside diameter is 80.0 mm, net mass 343.52 g, limiting speed reaches 7400 1/min, with a reference speed of 4750 1/min. The cage is of standard design, keeping the rollers evenly spaced and guided during rotation. The heavy series construction gives the bearing a higher load-carrying cross-section relative to its outside diameter, suiting applications where radial space is limited but load capacity must remain high. The standard cage ensures reliable roller guidance under the stated speed range, and running the bearing at or below the reference speed helps maintain stable thermal conditions. As it has no inner ring, a hardened and ground shaft surface is required to serve as the raceway.
