This component guides linear or rotary track motion through a double row angular contact ball bearing design with a particularly thick-walled outer ring, ball and cage assembly, and an inner ring. The outer ring is axially guided directly by the balls, giving the unit self-retaining properties without additional axial fixing parts. Bore diameter is 35.0 mm, outside diameter 68.0 mm, height 20.0 mm, and net mass 0.3 kg. Sealing is provided on both sides by lip seals, marked as 2RS, combining axial and radial sealing action. The double row ball arrangement allows the bearing to carry combined loads acting on the outer ring surface while maintaining accurate radial guidance through the thick-walled ring. The two-sided lip sealing restricts lubricant loss and limits ingress of contaminants, supporting stable running conditions once initial grease fill is applied. The self-retaining construction simplifies mounting, since the outer ring, ball and cage assembly, and inner ring form a complete guided unit without separate axial retention elements.
