71936 ACDGC/P4A Bearing Product Overview & Core Advantages
The 71936 ACDGC/P4A is a single-row angular contact ball bearing engineered for applications demanding high precision and superior performance under combined loads. Its defining characteristic is the 25° contact angle, which provides excellent capacity for handling substantial axial loads in one direction alongside radial loads. Manufactured to the stringent P4A tolerance class, this bearing offers exceptional running accuracy, low noise, and low vibration. The moderate preload (Class C) ensures high system rigidity and precise rotational control, making it an ideal choice for high-speed spindles and other precision machinery where reliability is paramount.

71936 ACDGC/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The 25° contact angle and moderate preload work in unison to deliver high system stiffness, effectively resisting deflection under combined radial and axial loads. The robust chrome steel construction supports high dynamic (35,775 lbf) and static (45,000 lbf) load ratings.
- High-Speed Capability: The lightweight, durable phenolic cage minimizes centrifugal forces and friction, contributing to a high limiting speed of 11,000 rpm. This makes the bearing suitable for demanding high-speed operations.
- Precision Performance: Manufactured to P4A tolerances, this bearing guarantees exceptional running accuracy, reduced vibration, and consistent performance in precision applications.
- Universal Matching Design (SU): This bearing is Universal Matchable, allowing for precise arrangement in sets of two or more (typically 3 bearings in a matched set) to achieve specific preload and stiffness characteristics without selective mounting.
71936 ACDGC/P4A Bearing Typical Application Areas
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Spindles: PCB drilling, high-frequency motor spindles.
- Industrial Pumps and Compressors: Applications requiring high axial load capacity and precision.
- Robotics and Automation: High-accuracy rotary joints and arm assemblies.
