Super Precision Angular Contact Ball Bearings S7208 ACD/P4ADGA

Super Precision Angular Contact Ball Bearings S7208 ACD/P4ADGA

The S7208 ACD/P4ADGA is a super precision angular contact ball bearing with a 40mm bore and 80mm outer diameter, crafted from durable chrome steel. It features a 25° contact angle and comes sealed for protection.

This bearing handles radial loads up to 11700 lbf and spins smoothly at speeds up to 41000 RPM. Its phenolic cage ensures quiet operation and long service life, even under extra light preload conditions.

Designed for universal matching, it can be arranged back-to-back, face-to-face, or tandem. The sealed design keeps grease in and contaminants out, making it low-maintenance.

Ideal for high-precision applications like machine tool spindles or robotics, where accuracy and reliability are key. It operates in temperatures from -30°C to 110°C and weighs just 0.75kg.

Compatible with SKF bearings, it’s a practical choice for replacements or upgrades. The set includes two matched bearings for versatile installation options.
