Super Precision Angular Contact Ball Bearings 71940 ACDGB/P4A

Super Precision Angular Contact Ball Bearings 71940 ACDGB/P4A

The 71940 ACDGB/P4A is a super precision angular contact ball bearing with a 200mm bore and 280mm outer diameter, crafted from high-quality chrome steel. Its 25° contact angle efficiently handles combined radial and axial loads, making it versatile for demanding applications.

This bearing supports dynamic radial loads up to 44775 lbf and operates smoothly at speeds reaching 6300 RPM. The phenolic cage ensures durability, while the open design allows for easy lubrication and maintenance.

With a P4A tolerance class, it offers exceptional precision for high-performance machinery. The bearing can be arranged in back-to-back, face-to-face, or tandem configurations, providing flexibility in setup.

Ideal for machine tools, spindles, or other precision equipment, it performs reliably in temperatures from -30°C to 110°C. Weighing 6.1kg, it’s robust yet manageable for its size. Interchangeable with SKF bearings, it’s a practical choice for replacements.
