Super Precision Angular Contact Ball Bearings 71830 ACD/HCP4

Super Precision Angular Contact Ball Bearings 71830 ACD/HCP4

The 71830 ACD/HCP4 is a super precision angular contact ball bearing with a 150mm bore and 190mm outer diameter, crafted from high-quality chrome steel. Its 25° contact angle efficiently manages combined radial and axial loads, while the ceramic balls reduce friction for smoother operation.

This bearing can handle dynamic radial loads up to 10980 lbf and speeds reaching 10000 RPM, making it suitable for high-performance applications. The phenolic cage ensures durability and maintains stability under stress.

Its open design allows for easy lubrication, and the P4 tolerance class guarantees exceptional accuracy. Ideal for precision machinery like CNC spindles or high-speed rotary tables, it operates reliably between -30°C and 110°C.

Weighing 0.98kg, it’s robust yet manageable for its size. Compatible with SKF bearings, it’s a versatile choice for replacements or upgrades in demanding environments.
