The 234448-M-SP axial angular contact ball bearing is a high-precision, double-direction, separable bearing specifically designed for demanding applications, primarily in machine tool spindles. With a bore diameter of 240mm, an outer diameter of 360mm, and a width of 144mm, this bearing provides exceptional rigidity and high axial load carrying capacity, critical for stable and accurate machine operation. Its design, often featuring a 60-degree contact angle and robust brass cage, enables high-speed performance and excellent vibration behavior. As a restricted tolerance (SP class) bearing, the 234448-M-SP is engineered for precise guidance of axial forces, frequently used in conjunction with radial cylindrical roller bearings to manage both axial and radial loads efficiently. This combination ensures optimal spindle performance, extended service life, and reliable operation in a wide range of industrial equipment.
