This insert ball bearing carries a spherical outer ring surface, allowing the unit to accommodate shaft misalignment while running on a bore diameter of 40.0 mm, outside diameter of 80.0 mm and width of 49.2 mm. Net mass is 0.609 kg, and the KRR sealing consists of contact seals on both sides that keep grease in and contaminants out. The self-aligning outer ring compensates for housing and mounting inaccuracies without inducing additional load on the balls, which keeps running behavior stable even when shaft deflection is present. With sealing integrated on both faces, the bearing is grease-lubricated for service and does not require external relubrication under normal conditions, making it suited for mounting in standard pillow block or flanged housings where a self-aligning insert bearing with a locking mechanism on the bore is needed.
