Super Precision Angular Contact Ball Bearings 71824 ACD/P4DGC

Super Precision Angular Contact Ball Bearings 71824 ACD/P4DGC

The 71824 ACD/P4DGC is a super precision angular contact ball bearing with a 120mm bore and 150mm outer diameter, crafted from durable chrome steel. Its 25° contact angle efficiently handles both radial and axial loads, making it versatile for high-performance applications.

With a dynamic radial load capacity of 11408 lbf, it supports heavy-duty operations while maintaining smooth rotation at speeds up to 16250 RPM. The phenolic cage ensures stability and reduces friction, enhancing longevity.

Designed for universal matching, this bearing can be arranged back-to-back, face-to-face, or tandem to suit different load requirements. Its moderate preload (Class C) offers balanced stiffness and precision.

Ideal for machine tools, spindles, or other high-speed equipment, it operates reliably in temperatures from -30°C to 110°C. Weighing 1.1kg, it’s robust yet manageable for its size. Compliant with P4 tolerance standards for exceptional accuracy.
