This double row angular contact ball bearing carries radial and axial loads in both directions from a single row unit through its two rows of balls arranged in an X-arrangement. Bore diameter is 25.0 mm, outside diameter 52.0 mm, width 20.6 mm, net mass 0.176 kg, limiting speed 10700 1/min. The design follows the X-life concept, with a steel sheet metal cage (JH), and the unit is fitted with seals (2HRS) on both sides. The integrated seals keep the grease fill in place and block contaminants from entering the raceways, so no external sealing arrangement is required at the housing. The double row X-arrangement gives the bearing a defined internal setup and reduced axial play compared to paired single row bearings, allowing it to take combined loads and moment loads while maintaining shaft and housing positioning with a single component.
