Super Precision Angular Contact Ball Bearings S71909 ACB/P4ADT

Super Precision Angular Contact Ball Bearings S71909 ACB/P4ADT

The S71909 ACB/P4ADT is a super precision angular contact ball bearing with a 45mm bore and 68mm outer diameter, crafted from durable chrome steel. It handles radial loads up to 2565 lbf and operates smoothly at speeds up to 41,000 RPM.

Its sealed design keeps grease in and contaminants out, while the phenolic cage ensures quiet, long-lasting performance. The 25° contact angle and matched arrangement (2 bearings) provide excellent stability under angular loads.

This bearing is ideal for high-precision applications like machine tool spindles or medical equipment, where accuracy and low friction are key. It works in temperatures from -30°C to 110°C and comes preloaded for immediate use.

Weighing 0.28kg, it’s lightweight yet robust, meeting P4A tolerance standards for precision engineering. Compatible with SKF equivalents, it’s a reliable choice for demanding setups.
