This insert ball bearing carries a spherical outer ring surface that seats in a housing, allowing angular compensation between shaft and housing during mounting and operation. Bore diameter is 40.0 mm, outside diameter 80.0 mm, width 30.2 mm, and net mass is 0.62 kg. The XL suffix indicates the extended inner ring design used for shaft fixing, while the NPP sealing consists of contact seals fitted on both sides of the bearing. The NPP sealing keeps the grease fill in place and restricts the ingress of dust and moisture, so the bearing can run without frequent relubrication. The spherical outer ring locating in a matching housing seat accommodates minor shaft misalignment, which simplifies alignment during installation and reduces the risk of edge loading on the balls and raceways. The extended inner ring (XL) design provides a shaft-locking arrangement suited to mounting on plain shaft ends.
