71936 ACDGB/P4A Bearing Product Overview & Core Advantages
The 71936 ACDGB/P4A is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and reliability. This single-row bearing features a 25° contact angle and is supplied with a light preload (Class B), making it ideal for applications requiring high rigidity and precise rotational accuracy. Its open seal type allows for optimal lubrication management in controlled environments. Manufactured to P4A tolerance class, this bearing delivers superior running accuracy and is universally matchable (SU), enabling the creation of preloaded sets for enhanced system stiffness.

71936 ACDGB/P4A Bearing Structural Features & Performance Benefits
High Precision & Rigidity: The P4A tolerance class ensures minimal runout and vibration, while the light preload eliminates internal clearance, providing superior system stiffness and precise shaft positioning.
Optimized Load Capacity: With a 25° contact angle, this bearing efficiently handles combined radial and axial loads in one direction. The radial dynamic load rating of 35,775 lbf and static load rating of 45,000 lbf ensure reliable performance under significant loads.
High-Speed Capability: The phenolic cage provides excellent strength-to-weight ratio and operates effectively at high speeds, contributing to the bearing's limiting speed of 16,250 rpm.
Precision Matching: As a universally matchable (SU) bearing, multiple units can be arranged in sets (typically 3 bearings) to achieve specific preload conditions and optimize system performance.
