Additional Details
Single row cylindrical ball bearings (NUPs) are designed to handle high radial loads combined with high speeds. They feature two combined flanges on the outer ring and one combined and one removable flange on the inner ring. NUP bearings can accommodate shaft positions in both directions. A key feature is their separable design, which simplifies installation and allows for easy replacement of bearing components.
