Super Precision Angular Contact Ball Bearings S7017 ACD/P4ATGA

The S7017 ACD/P4ATGA is a super precision angular contact ball bearing with an 85mm bore and 130mm outer diameter, crafted from durable chrome steel. It handles radial loads up to 31050 lbf and operates smoothly at speeds up to 17000 RPM.

Its sealed design keeps grease in and contaminants out, while the phenolic cage ensures quiet, long-lasting performance. The bearing works well in temperatures from -30°C to 110°C and comes preloaded for extra light applications.

This model is part of a matched set of three, allowing versatile arrangements like back-to-back or face-to-face. Ideal for high-precision machinery like spindles or CNC equipment where accuracy is key.

Weighing 2.73kg, it’s robust yet manageable for its size. Compliant with P4A tolerance standards for reliable performance.
