Carries radial and axial loads on a cylindrical shaft while compensating for shaft misalignment through a steel aligning ring seated in a spherical outer ring housing. This insert ball bearing has a bore diameter of 20.0 mm, an outside diameter of 55.0 mm and a net mass of 0.188 kg, with a cylindrical outer ring and P seals fitted on both sides. The double-side P sealing keeps grease inside the bearing and blocks contaminants from entering, so the bearing can run without additional protective covers on the housing. The spherical seating of the aligning ring allows the bearing to accommodate shaft deflection or housing misalignment without introducing extra internal stress, making it suitable for mounting where precise shaft-to-housing alignment cannot be guaranteed.
