This needle roller bearing is designed to carry radial loads in a compact cross-section, with a heavy-series construction giving increased load capacity compared to standard series. Outside diameter is 58.0 mm, net mass 145.78 g, and the design incorporates a standard cage for roller guidance and spacing. Limiting speed reaches 10200 1/min, with a reference speed of 6200 1/min. The heavy-series build suits applications where radial space is limited but higher load-carrying capacity is required than a standard-series needle bearing can provide. The standard cage ensures consistent roller positioning and smooth running up to the stated speed limits, while the defined limiting and reference speeds allow proper thermal and lubrication planning during operation.
