Super Precision Angular Contact Ball Bearings S7018 ACD/P4ADGC

Super Precision Angular Contact Ball Bearings S7018 ACD/P4ADGC

The S7018 ACD/P4ADGC is a super precision angular contact ball bearing with a 90mm bore and 140mm outer diameter, crafted from durable chrome steel. It handles radial loads up to 27225 lbf and operates smoothly at speeds up to 15000 RPM.

Its 25° contact angle and sealed design ensure reliable performance under moderate preload, while the phenolic cage reduces friction. The bearing works in temperatures from -30°C to 110°C and comes pre-lubricated with grease.

This universal matching set includes two bearings, suitable for back-to-back, face-to-face, or tandem arrangements. Ideal for high-precision applications like machine tools or spindle drives.

Weighing 2.33kg, it meets P4A tolerance standards for exceptional accuracy. Interchangeable with SKF bearings for easy replacement.
