This single row angular contact ball bearing carries balls positioned at a defined contact angle to handle combined radial and axial loads in one direction. Bore diameter is 85.0 mm, outside diameter 180.0 mm, width 41.0 mm, and net mass 4.8 kg. The X-life design provides increased load rating within the standard envelope. The bearing uses a solid brass cage (MP), permitting a limiting speed of 6400.0 1/min and a reference speed of 4100.0 1/min. The solid brass cage keeps ball spacing stable at higher speeds and under acceleration, supporting reliable operation up to the stated limiting speed. Being a single row angular contact design, axial load capacity is directional, so the bearing should be mounted and paired according to the required load direction, often in a back-to-back or face-to-face arrangement with a matching bearing for full axial support in both directions. The X-life execution allows for a compact footprint while sustaining higher loads at the given dimensions.
