Super Precision Angular Contact Ball Bearings S7020 ACD/P4ADBA

Super Precision Angular Contact Ball Bearings S7020 ACD/P4ADBA

The S7020 ACD/P4ADBA is a super precision angular contact ball bearing with a 100mm bore and 150mm outer diameter, crafted from durable chrome steel. Its compact design measures 100mm×150mm×48mm, making it suitable for tight spaces.

This bearing handles radial loads up to 28575 lbf and spins smoothly at speeds up to 16250 RPM. With a 25° contact angle and extra light preload, it offers excellent stability and precision.

Its sealed design keeps grease in and contaminants out, while the phenolic cage ensures quiet operation. The matched pair arrangement (DB) enhances performance in high-precision applications.

Ideal for machine tools, spindles, or other high-speed equipment requiring accuracy. It operates in temperatures from -30°C to 110°C and is interchangeable with SKF bearings. Weighing 2.55kg, it’s robust yet manageable for its size.
