The FAG B7009CTP4AUM is a high-precision angular contact ball bearing, specifically designed for demanding spindle applications requiring high rotational accuracy and rigidity. This bearing features a 45 mm bore diameter, 68 mm outer diameter, and 12 mm width. It incorporates a 15° contact angle (C) and a robust textile laminate cage (T), typically made of phenolic resin. The P4A precision class ensures superior dimensional and running accuracy, while the UM designation signifies a universal match with light preload, making it ideal for mounting in sets to achieve specific preload and stiffness requirements.
