This needle roller bearing carries radial loads through a single row of rollers guided by a standard cage, with a bore diameter of 55.0 mm, outside diameter of 85.0 mm and width of 28.0 mm. Net mass is 0.562 kg. Radial internal clearance is CN (Group N). Limiting speed is rated at 6900 1/min, while the reference speed reaches 4000 1/min. The bearing has no integrated sealing, so shaft or housing components must provide protection against contamination and retain lubricant. Radial internal clearance in group CN suits standard mounting conditions without special preload requirements. The standard cage ensures roller spacing and guidance under radial load, making the design suitable for applications where a compact needle roller bearing with a defined radial section is needed and where sealing and lubrication are supplied externally.
