Super Precision Angular Contact Ball Bearings S7020 ACD/P4ADGC

Super Precision Angular Contact Ball Bearings S7020 ACD/P4ADGC

The S7020 ACD/P4ADGC is a super precision angular contact ball bearing with a 100mm bore and 150mm outer diameter, designed for high-performance applications. It features a 25° contact angle and sealed design, offering reliable protection against contaminants.

Made from chrome steel with a phenolic cage, it handles dynamic radial loads up to 28575 lbf and spins smoothly at speeds up to 16250 RPM. Its moderate preload (Class C) ensures stable operation under demanding conditions.

The bearing comes in a universal matched set of two, allowing flexible arrangements like back-to-back or face-to-face mounting. Ideal for machine tools or high-speed spindles where precision and durability are key.

Weighing 2.55kg, it operates in temperatures from -30°C to 110°C and is interchangeable with SKF bearings. The grease lubrication simplifies maintenance for long-term use.
