Super Precision Angular Contact Ball Bearings S71916 CDGA/P4A

Super Precision Angular Contact Ball Bearings S71916 CDGA/P4A

The S71916 CDGA/P4A is a super precision angular contact ball bearing with an 80mm bore and 110mm outer diameter, crafted from high-quality chrome steel. Its compact 16mm width makes it suitable for tight spaces, while the 15° contact angle ensures efficient load handling.

This bearing handles dynamic radial loads up to 8190 lbf and spins smoothly at speeds up to 28,000 RPM. The phenolic cage provides durability, and the sealed design keeps grease in place for long-lasting performance.

Designed for precision applications, it works well in temperatures from -30°C to 110°C. The P4A tolerance class ensures high accuracy, making it ideal for machine tools or high-speed spindles.

Weighing just 0.38kg, it’s lightweight yet robust. It can be paired in back-to-back, face-to-face, or tandem arrangements for versatile use. Interchangeable with SKF bearings, it’s a reliable choice for replacements.
