This angular contact ball bearing is supplied as a matched pair arranged for double direction axial load support, meaning it can take axial loads from both directions along the shaft. Bore diameter is 20.0 mm, outside diameter 52.0 mm, and the paired set has a width of 56.0 mm, with a net mass of 0.622 kg. Sealing is provided by lip seals on both sides (2RS), protecting the raceways and balls from contaminants and retaining lubricant inside the bearing. The double direction arrangement makes this pairing suitable for applications where axial forces act alternately or simultaneously from opposite directions along the shaft axis, while the matched-pair design ensures correct internal preload and alignment between the two units when mounted together. The integrated lip seals allow operation in environments where dust or moisture ingress must be limited without the need for external sealing arrangements, and the fixed pairing simplifies mounting since the two bearings are supplied ready to install as a set rather than requiring separate selection and matching.
