This insert ball bearing carries a spherical outer ring seated in a non-locating design, with a drive slot machined into the inner ring for torque transmission through a shaft collar or similar fixing element. Bore diameter is 35.0 mm, outside diameter 72.0 mm, width 37.7 mm, and net mass is 0.42 kg. Sealing is provided on both sides by R-type seals (KRR), protecting the raceway and ball complement from contamination. The spherical outer ring allows the bearing to self-align within its housing, compensating for minor shaft misalignment without imposing extra load on the raceway. As a non-locating bearing, it permits axial displacement of the outer ring relative to the housing, making it suitable where thermal expansion or shaft length variation needs to be accommodated. The two-sided KRR sealing retains the internal grease fill and keeps out dust and moisture, supporting maintenance-light operation in applications where the inner ring is driven directly via the slot rather than through a separate locking collar.
