Spindle Bearings Made Of Rolling Bearing Steel B7218-E-T-P4S-UL

Spindle bearings are a particular type of single-row angular contact ball bearings. They are often used in manufacturing machine tools and various applications with high to extremely high demands for the accuracy or permissible speed required by the mounting/ bearing installation. Compared with standard angular contact ball bearings, spindle bearings are distinguished by the contact angle, the tolerance classes, and the cage design. Spindle bearings can be delivered with a contact angle of 15° or 25°. Withstand high load ratings and are suitable for temperatures up to circa +80°C in the long run and up to circa +120°C in the short run. The steel is wear-resistant, shock-resistant, conductive, and magnetic.
