Description
Insert ball bearing designed to carry radial loads while accommodating an eccentric locking collar for shaft fixation. The GRAE25-XL-NPP-B has a bore diameter of 25.0 mm, an outside diameter of 52.0 mm, a width of 21.4 mm, and a net mass of 0.19 kg. The extended inner ring (XL) allows secure clamping onto the shaft without additional fixing elements. Sealing type NPP provides contact seals on both sides, protecting the raceway and balls from dust and moisture ingress while retaining internal grease. This construction suits applications where the shaft may experience slight misalignment, thanks to the spherical outer ring profile working with the housing. The sealed design and self-aligning capability make it suitable for mounting in plummer blocks or flanged housings where relubrication access is limited.
