The FAG B71908-C-2RSD-T-P4S-UL is a high-precision angular contact ball bearing designed for demanding spindle applications. Featuring a 40 mm bore diameter, 68 mm outer diameter, and 15 mm width, this bearing has a 15° contact angle (C) for high axial and radial rigidity. It is equipped with 2RSD contact seals on both sides to protect against contaminants and retain lubricant, making it suitable for environments requiring enhanced sealing. The 'T' indicates a cage made of textile laminate (phenolic resin), and 'P4S-UL' signifies a high-precision class (P4S) and universal design (UL) for paired mounting in any arrangement. This bearing is ideal for machine tool spindles and other high-speed, high-precision rotating equipment.
