SD250AR0 Bearing Product Overview & Core Advantages
The SD250AR0 is a thin-section angular contact ball bearing engineered for applications requiring high precision and space optimization. Manufactured with stainless steel rings and balls and a brass cage, this bearing is designed to handle combined radial and axial loads simultaneously. Its 30° contact angle provides excellent axial load capacity while maintaining operational stability. As part of the Reali-Slim series, it offers a compact cross-section with a 25" bore and 26" outside diameter, making it ideal for high-rigidity applications where weight and space are critical constraints.
