This insert ball bearing carries a spherical outer ring that seats in a housing, allowing self-alignment without acting as a locating bearing. The inner ring features a drive slot for shaft-side torque transmission, with a bore of 20.0 mm, an outside diameter of 47.0 mm, a width of 34.1 mm, and a net mass of 0.15 kg. Sealing on both sides is realized through R seals (KRR), keeping contaminants out while retaining internal lubrication. The spherical outer ring lets the bearing accommodate slight shaft misalignment or housing bore deviation, which simplifies alignment during installation. The drive slot in the inner ring provides positive engagement for torque transfer through set screws or similar fixing elements, while the double-sided R sealing (KRR) protects the internal grease fill and rolling elements from dust and moisture ingress during operation.
