Super Precision Angular Contact Ball Bearings S71919 ACB/P4A

Super Precision Angular Contact Ball Bearings S71919 ACB/P4A

The S71919 ACB/P4A is a super precision angular contact ball bearing with a 95mm bore and 130mm outer diameter, crafted from high-grade chrome steel. Its 25° contact angle efficiently manages combined radial and thrust loads, while the sealed design keeps lubrication in and contaminants out.

This bearing can handle dynamic radial loads up to 3870 lbf and reaches speeds of 12,000 RPM, making it suitable for high-performance applications. The phenolic cage ensures smooth operation and reduces friction, enhancing durability.

With a P4 tolerance class (equivalent to ABEC-7), it offers exceptional accuracy for precision machinery. Ideal for use in spindle drives, CNC machines, or other equipment requiring tight tolerances and reliable performance.

Weighing 0.64kg, it’s robust yet manageable for its size. The bearing comes pre-lubricated and operates efficiently in temperatures from -30°C to 110°C. It’s also interchangeable with SKF models, providing flexibility for replacements.
