This angular contact ball bearing carries radial and axial loads simultaneously through two rows of balls set at a contact angle, giving it a defined stiffness in both directions from a single unit. Bore diameter is 25.0 mm, outside diameter 52.0 mm, width 20.6 mm, and net mass 0.172 kg. The X-life design uses a plastic cage (TVH) and permits a limiting speed of 10700 1/min. Seals fitted on both sides (2HRS) keep the internal grease fill protected and retain lubricant over the service life, so no external relubrication path is required. The double-row arrangement suits mounting positions where combined loading must be taken up without a second single-row bearing, while the plastic cage reduces friction and mass compared with a machined cage of the same size.
