Super Precision Angular Contact Ball Bearings S7020 ACD/P4AQGA

The S7020 ACD/P4AQGA is a super precision angular contact ball bearing with a 100mm bore and 150mm outer diameter, designed for high accuracy applications. Its 25° contact angle and sealed design ensure smooth operation under angular loads.

Made from chrome steel with a phenolic cage, it handles radial loads up to 46800 lbf and spins at speeds up to 16250 RPM. The extra light preload (Class A) reduces friction for efficient performance.

This bearing comes in a matched set of four, allowing universal arrangements like back-to-back or face-to-face mounting. Ideal for machine tools or high-speed spindles where precision is key.

Weighing 5.09kg, it operates in temperatures from -30°C to 110°C and is lubricated with grease for easy maintenance. Compliant with P4A tolerance standards for reliable performance.
