Super Precision Angular Contact Ball Bearings S7018 ACD/P4AQBCC

Super Precision Angular Contact Ball Bearings S7018 ACD/P4AQBCC

The S7018 ACD/P4AQBCC is a super precision angular contact ball bearing with a 90mm bore and 140mm outer diameter, crafted from durable chrome steel. It manages radial loads up to 44775 lbf and operates smoothly at speeds up to 15000 RPM.

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

This set includes four matched bearings (QBC arrangement), ideal for high-precision applications like machine tool spindles or aerospace systems. It works in temperatures from -30°C to 110°C.

Weighing 4.67kg, it’s robust yet designed for precision. Compliant with P4A tolerance standards for reliable performance. Interchangeable with SKF bearings for easy replacement.
