Super Precision Angular Contact Ball Bearings 71936 CDGA/P4

Super Precision Angular Contact Ball Bearings 71936 CDGA/P4

The 71936 CDGA/P4 is a super precision angular contact ball bearing with a 280mm bore and 380mm outer diameter, crafted from high-quality chrome steel. Its 15° contact angle and open design ensure smooth operation under angular loads.

This bearing handles dynamic radial loads up to 37800 lbf and spins efficiently at speeds up to 7500 RPM. The phenolic cage offers durability while keeping weight manageable at 4.2kg.

With a P4 tolerance class, it delivers exceptional accuracy for demanding applications. The extra light preload (Class A) ensures minimal friction and consistent performance.

Ideal for high-precision machinery like spindles or machine tools, it operates reliably between -30°C and 110°C. It can be arranged back-to-back, face-to-face, or tandem for versatile use.

The bearing is interchangeable with SKF models, making replacements straightforward. Its universal matching capability allows it to work seamlessly in matched sets of four.
