Super Precision Angular Contact Ball Bearings S7015 ACD/P4AQBCC

Super Precision Angular Contact Ball Bearings S7015 ACD/P4AQBCC

The S7015 ACD/P4AQBCC is a super precision angular contact ball bearing with a 75mm bore and 115mm outer diameter, crafted from durable chrome steel. It handles radial loads up to 29925 lbf and operates smoothly at speeds up to 22000 RPM.

Its sealed design keeps grease in and contaminants out, while the phenolic cage ensures quiet, long-lasting performance. The 25° contact angle and moderate preload (Class C) provide excellent stability under angular loads.

This bearing comes in a matched set of four (QBC arrangement), ideal for high-precision applications like machine tool spindles or robotics. It works in temperatures from -30°C to 110°C and is interchangeable with SKF models.

Weighing 2.56kg, it offers robust performance in a compact size. The P4A tolerance class guarantees exceptional precision for demanding industrial uses.
