This insert ball bearing carries radial load through a spherical outer ring seated in a spherical housing bore, allowing self-alignment at the outer ring interface. The inner ring is secured to the shaft by an eccentric locking collar, giving a positive axial fixation without a separate sleeve. Bore diameter is 90.0 mm, outside diameter 190.0 mm, width 77.5 mm, and the unit weighs 8.07 kg. Sealing is provided by KRR seals fitted on both sides of the bearing, sealing rubbing lips that keep out contaminants and retain lubricant at the seal contact. The spherical outer ring surface permits a degree of angular misalignment between shaft and housing, which is useful where shaft deflection or housing bore alignment cannot be held to close tolerance. The eccentric locking collar allows mounting and removal from one side of the bearing without special tooling, and it locks the inner ring firmly to the shaft to prevent creep under load. With seals on both faces, the bearing is suited for running with grease lubrication in environments where ingress protection at the shaft passage is required.
