Super Precision Angular Contact Ball Bearings S7020 CD/P4ADGA

Super Precision Angular Contact Ball Bearings S7020 CD/P4ADGA

The S7020 CD/P4ADGA is a super precision angular contact ball bearing with a 100mm bore and 150mm outer diameter, crafted from high-grade chrome steel. Its 15° contact angle and sealed design ensure smooth operation under radial loads up to 30375 lbf.

With a maximum speed of 10000 RPM and grease lubrication, it performs reliably in temperatures from -30°C to 110°C. The phenolic cage adds durability while keeping the bearing lightweight at 2.55kg.

This bearing comes in a matched set of two, suitable for universal mounting configurations like back-to-back or face-to-face. Ideal for high-precision applications such as machine tools or spindle drives where accuracy is key.

Compliant with P4A tolerance class, it offers extra-light preload for minimal friction. Its interchangeable design with SKF bearings makes it a versatile choice for replacements or upgrades.
