Super Precision Angular Contact Ball Bearings 7011 ACB/HCP4ADGA

Super Precision Angular Contact Ball Bearings 7011 ACB/HCP4ADGA

The 7011 ACB/HCP4ADGA is a super precision angular contact ball bearing with a 55mm bore and 90mm outer diameter, crafted from durable chrome steel. Its 25° contact angle and ceramic balls ensure smooth operation under radial loads up to 4770 lbf.

This bearing spins at speeds up to 34,000 RPM, thanks to its phenolic cage and extra-light preload. The open design allows easy lubrication, while the universal matching feature offers flexibility in arrangement (back-to-back, face-to-face, or tandem).

Ideal for high-speed applications like machine tool spindles or precision instruments, it handles temperatures from -30°C to 110°C. Weighing 0.8kg, it’s a robust yet lightweight choice for demanding setups.

Compliant with P4A tolerance standards, it’s interchangeable with SKF bearings, making replacements hassle-free. The matched set of two bearings ensures consistent performance in paired configurations.
