The INA-FAG B71900CTP4AUM is a high-precision angular contact ball bearing, specifically designed for demanding machine tool spindle applications requiring exceptional running accuracy and high speeds. This FAG spindle bearing features a 10 mm inner diameter, 22 mm outer diameter, and 6 mm width. It is characterized by a 15° contact angle (C), P4A precision class, and a universal design (T) which allows for pairing in various arrangements, providing a medium preload (UM) when mounted. The bearing utilizes a textile laminate cage (T) and is outer ring piloted, ensuring robust and reliable performance in high-speed, high-precision environments. It offers a limiting speed of 63,000 rpm with grease lubrication and 95,000 rpm with oil-air lubrication.
