71810 ACD/P2DBCVT105F2 Bearing Product Overview & Core Advantages
The 71810 ACD/P2DBCVT105F2 is a precision angular contact ball bearing designed for demanding applications requiring high rigidity and accurate rotational performance. This duplex back-to-back (DB) arrangement is preloaded to provide moderate preload (Class C), ensuring exceptional system stiffness and minimal axial and radial runout. It is engineered to handle combined loads—simultaneous radial and axial forces—with high efficiency, making it ideal for high-speed spindles and precision machinery where positional accuracy is critical. The compact design, with a 50mm bore and 65mm outside diameter, offers a space-saving solution without compromising on performance.

71810 ACD/P2DBCVT105F2 Bearing Structural Features & Performance Benefits
- High Rigidity & Stability: The duplex back-to-back (DB) arrangement with moderate preload creates a rigid bearing system that effectively resists moment loads and maintains shaft positioning under combined loads.
- Superior Load Capacity: With a 25° contact angle, this bearing is optimized to support significant axial loads in one direction while also handling substantial radial loads, making it suitable for applications with complex loading conditions.
- High-Speed Capability: The lightweight phenolic cage reduces centrifugal forces, and the precision-ground chrome steel components contribute to smooth operation, enabling a high limiting speed of 41,000 rpm.
- Precision Performance: Manufactured to tight tolerance class N with narrow bore and OD tolerances, this bearing ensures high running accuracy and low vibration for precision applications.
- Optimized Lubrication: The bearing is pre-lubricated with a specific grease (T105F2) that provides reliable performance within its designated temperature range from -30°C to 110°C.
