Description

This spindle bearing carries a 15° contact angle and is designed for precise axial and radial location under high-speed rotation. Bore diameter is 90.0 mm, outside diameter 125.0 mm, width 18.0 mm, and net mass 0.546 kg. The cage is executed in version T, and the bearing is supplied without sealing, allowing direct oil or grease feed to the rolling contact. Manufactured to restricted (P4S) tolerances, this bearing is matched and adjusted for mounting in pairs or sets, ensuring consistent preload and running accuracy across the set. The 15° contact angle gives it a balance of axial and radial load-carrying capability suited to combined loading conditions. As it is supplied without integrated sealing, external sealing and a controlled lubrication supply must be provided by the housing design.
