Description
This insert ball bearing carries a cylindrical bore with a bore diameter of 50.0 mm, outside diameter of 90.0 mm, and width of 30.2 mm, with a net mass of 0.729 kg. The bearing is fitted with NPP sealing on both sides, protecting the internal geometry from contamination while retaining grease inside the bearing. The spherical outer ring surface allows self-alignment within a housing, compensating for minor shaft misalignment during operation. With NPP sealing already integrated, the bearing is supplied ready for grease lubrication and requires no additional sealing components during mounting on the shaft.
