This insert ball bearing carries a spherical outer ring surface, allowing it to seat and self-align within a housing while the shaft connection is made through an adapter sleeve rather than a straight bore fit. Outside diameter is 110.0 mm, width is 40.0 mm, and net mass is 1.58 kg. Sealing is provided by 2RSR seals fitted on both sides of the bearing. The adapter sleeve mounting method permits positioning anywhere along a shaft without requiring a shoulder or precise shaft tolerance, simplifying installation and dismounting. The spherical outer ring geometry accommodates a degree of misalignment between shaft and housing, which is useful where shaft deflection or minor mounting inaccuracies occur. The 2RSR sealing arrangement on both sides retains internal lubricant and restricts entry of contaminants, supporting operation with minimal maintenance once the initial grease fill is in place.
