Super Precision Angular Contact Ball Bearings 7020 CDGC/P4A

Super Precision Angular Contact Ball Bearings 7020 CDGC/P4A

The 7020 CDGC/P4A is a super precision angular contact ball bearing with a 100mm bore and 150mm outer diameter, crafted from high-quality chrome steel. Its 15° contact angle efficiently manages combined radial and axial loads, suitable for high-speed applications.

With a dynamic radial load capacity of 18720 lbf, it spins smoothly at speeds up to 20,000 RPM. The phenolic cage ensures durability while keeping the bearing lightweight at just 1.26kg.

The open design allows easy lubrication, and the P4A tolerance class guarantees precise performance. It operates reliably in temperatures ranging from -30°C to 110°C.

Ideal for machine tools or spindle applications, this bearing can be matched in sets for back-to-back, face-to-face, or tandem arrangements. Compatible with SKF models for easy replacement.
