This single row angular contact ball bearing carries loads at a defined contact angle, taking combined radial and axial loads in one direction. Bore diameter is 35.0 mm, outside diameter 80.0 mm, width 21.0 mm, net mass 0.498 kg. The bearing uses a solid brass cage (MP) and is manufactured to the X-life standard, which raises the load carrying capacity of the rolling elements compared to a standard design. Limiting speed is rated at 15500 1/min, with a reference speed of 7900 1/min. The solid brass cage guides the balls securely at higher speeds and under axial loading, keeping the cage stable under acceleration and load reversal. Since it is a single row design, mounting in pairs is required if axial loads act in both directions or if a stiffer, more rigid arrangement is needed. The X-life execution allows for a higher load rating within the same envelope dimensions, making this bearing suitable where shaft speeds approach the reference speed value and where axial load handling in one direction is the main requirement.
