This needle roller bearing carries radial loads in a compact cross-section, with an outside diameter of 52.0 mm and a width of 20.0 mm, weighing 91.37 g. It is a single row design built to DIN 617/ISO 1206, fitted with a standard cage. The limiting speed reaches 11100 1/min, with a reference speed of 6400 1/min. The bearing has no sealing, so it requires a clean operating environment and external protection against contamination, along with a separate lubrication supply. The single row arrangement without a flanging ring keeps the radial section low, making the design suitable where mounting space is limited and the shaft or housing provides axial location of the rollers.
