RNU 080821R NR RICH Cylindrical Roller Bearing Without Inner Ring – 40 x 75 x 21 mm – High Radial Capacity with Retaining Ring Groove

Engineered for applications demanding exceptional radial load capacity and compact design flexibility. The RNU 080821R NR RICH cylindrical roller bearing, supplied without an inner ring, is designed to utilize a hardened shaft journal as its inner raceway. This allows for a larger shaft diameter within a given bearing envelope, making it ideal for systems with limited radial space. With precise dimensions of 40 mm inner diameter, 75 mm outer diameter, and a width of 21 mm, this bearing ensures robust and reliable rotational support.

This RICH bearing features a durable steel cage that precisely guides the cylindrical rollers, contributing to smooth operation and extended service life. A key characteristic of this model is the groove on its outer ring with a retaining ring, which simplifies axial positioning and assembly. This integrated feature provides a secure fit and enhances the overall stability of the bearing in its housing.

Manufactured in China by RICH, this cylindrical roller bearing weighs 0.39 kg. Its design is perfect for heavy-duty applications such as gearboxes, industrial pumps, and rolling mills, where high radial loads, precision, and ease of mounting are crucial.
