This insert ball bearing carries radial loads through a cylindrical outer ring fitted with a steel aligning ring, allowing the outer ring to self-align in a housing. The inner ring is secured to the shaft by an eccentric locking collar, and P seals are fitted on both sides. Bore diameter is 30.0 mm, outside diameter 72.0 mm, width 37.2 mm, and net mass 0.49 kg. The steel aligning ring compensates for angular misalignment between shaft and housing, so the unit tolerates shaft deflection without binding. The eccentric locking collar gives a positive, easily released connection to the shaft, and the double-sided P seals restrict the ingress of contaminants while retaining the grease fill for the running surfaces.
