Super Precision Angular Contact Ball Bearings 71822 ACDGA/HCP2

Super Precision Angular Contact Ball Bearings 71822 ACDGA/HCP2

The 71822 ACDGA/HCP2 is a super precision angular contact ball bearing with a 110mm bore and 140mm outer diameter, crafted from durable chrome steel. Its compact 16mm width makes it suitable for space-constrained applications.

With a 25° contact angle and ceramic balls, it handles radial loads up to 6795 lbf and spins smoothly at speeds up to 16,000 RPM. The extra light preload ensures minimal friction during operation.

The open design allows easy lubrication, while the phenolic cage offers quiet and efficient performance. It works reliably in temperatures from -30°C to 110°C.

Ideal for high-precision machinery like CNC spindles or medical equipment, this bearing is interchangeable with SKF models. Weighing 0.45kg, it’s lightweight yet robust for demanding applications.
