Description
This insert ball bearing carries a spherical outer ring surface, allowing it to sit in a corresponding housing and compensate for shaft misalignment. Bore diameter is 20.0 mm, outside diameter 47.0 mm, width 21.4 mm, and net mass is 0.16 kg. The XL suffix indicates extended inner ring dimensions, providing an extended contact area for shaft fixation. Sealing type NPP consists of contact seals on both sides, protecting the internal geometry against contamination and retaining the grease fill applied by the manufacturer. The design suits shaft mounting through set screws typical of insert ball bearing units, and the sealed construction reduces the need for maintenance intervention during operation.
