This insert ball bearing transmits radial and axial loads through a spherical outer ring, which allows self-alignment within its housing seat. The GSH20-XL-2RSR-B has an outside diameter of 47.0 mm, a width of 15.0 mm, and a net mass of 0.15 kg. Shaft location is achieved by means of an adapter sleeve, and the bearing is fitted with RSR seals on both sides. The spherical outer ring surface permits the bearing to accommodate misalignment between the shaft and housing, simplifying installation and reducing sensitivity to mounting inaccuracies. The two-sided RSR sealing protects the internal raceways and rolling elements from dust and moisture ingress while retaining the internal lubricant, and adapter sleeve mounting allows the bearing to be fixed at any point along a plain shaft without the need for a stepped or grooved shaft surface.
