Super Precision Angular Contact Ball Bearings 7020 CB/P4A

Super Precision Angular Contact Ball Bearings 7020 CB/P4A

The 7020 CB/P4A is a super precision angular contact ball bearing with a 100mm bore and 150mm outer diameter, crafted from high-quality chrome steel. It handles both radial and angular loads, with a dynamic radial load capacity of 6660 lbf and a static radial load of 6075 lbf.

Designed for high-speed operations, it can reach up to 17,000 RPM while maintaining smooth performance. The open seal type allows for easy lubrication, and the phenolic cage ensures durability and reduced friction.

With a 15° contact angle, this bearing is ideal for matched arrangements and preload applications. Its P4 tolerance class (ABEC-7) ensures exceptional precision, making it suitable for machine tools and high-performance industrial equipment.

Weighing 1.36kg, it’s robust yet manageable for its size. Compatible with SKF bearings, it’s a reliable choice for replacements. Works well in temperatures from -30°C to 110°C.
