Super Precision Angular Contact Ball Bearings S7020 ACD/P4AQBCA

Super Precision Angular Contact Ball Bearings S7020 ACD/P4AQBCA

The S7020 ACD/P4AQBCA is a super precision angular contact ball bearing with a 100mm bore and 150mm outer diameter, crafted from durable chrome steel. It measures 100mm×150mm×96mm and comes in a matched set of four bearings for balanced performance.

This bearing handles radial loads up to 46800 lbf and spins smoothly at speeds up to 16250 RPM. Its 25° contact angle and extra-light preload ensure precise operation in demanding applications.

The sealed design keeps grease in and contaminants out, while the phenolic cage offers quiet, long-lasting use. It works well in temperatures from -30°C to 110°C.

Ideal for high-precision machinery like CNC spindles or grinding equipment, where accuracy and reliability are key. Weighing 5.09kg, it’s robust yet manageable for its size. Compliant with P4A tolerance standards for top-tier performance.

Interchangeable with SKF bearings, it’s a practical choice for replacements or upgrades. The matched set ensures consistent performance across all four units.
