This insert ball bearing carries a radial load through a spherical outer ring surface fitted with a rubber interliner, allowing the housing seat to compensate for minor misalignment. The bore diameter is 20.0 mm, the outside diameter measures 65.1 mm, and the unit weighs 0.245 kg net. The inner ring is secured to the shaft by an eccentric locking collar, giving a fixed, self-locking connection without the need for a separate fastening screw. Both sides are fitted with P seals, protecting the rolling elements from dust and moisture ingress in the running clearance. The design suits mounting positions where the shaft may run with slight deflection, since the interliner absorbs small angular deviations without transmitting them into the bearing seat. The eccentric collar locking method allows straightforward fitting and removal from one side of the housing, which is useful where access to the shaft end is limited.
