Super Precision Angular Contact Ball Bearings S7020 ACDGB/P4A

Super Precision Angular Contact Ball Bearings S7020 ACDGB/P4A

The S7020 ACDGB/P4A is a super precision angular contact ball bearing with a 100mm bore and 150mm outer diameter, crafted from high-grade chrome steel. It handles radial loads up to 17842 lbf and operates smoothly at speeds up to 16250 RPM.

Its sealed design keeps grease in and contaminants out, while the phenolic cage ensures quiet, long-lasting performance. The 25° contact angle provides excellent stability for angular loads.

This bearing is part of a universal matching set, allowing flexible arrangements like back-to-back or face-to-face. Ideal for high-precision applications such as machine tool spindles or high-speed rotary tables.

Weighing 1.27kg, it’s designed for temperatures from -30°C to 110°C and meets strict P4A tolerance standards for reliable operation.
