Super Precision Angular Contact Ball Bearings 71819 CDGA/P4

Super Precision Angular Contact Ball Bearings 71819 CDGA/P4

The 71819 CDGA/P4 is a super precision angular contact ball bearing with a 95mm bore and 120mm outer diameter, crafted from durable chrome steel. It measures just 13mm wide, making it compact yet robust for its size.

This bearing handles radial loads up to 4972 lbf and spins smoothly at speeds up to 15000 RPM. Its 15° contact angle ensures efficient load distribution, while the phenolic cage offers quiet operation.

Designed for extra light preload (Class A), it’s ideal for high-precision applications. The open seal allows easy lubrication, and it operates reliably in temperatures from -30°C to 110°C.

Interchangeable with SKF bearings, it’s suited for paired arrangements like back-to-back or face-to-face setups. Perfect for machine tools or precision gearboxes where accuracy is key. Weighing 0.29kg, it balances performance with portability.
