Super Precision Angular Contact Ball Bearings S71909 ACE/P4ADBA

Super Precision Angular Contact Ball Bearings S71909 ACE/P4ADBA

The S71909 ACE/P4ADBA is a super precision angular contact ball bearing with a 45mm bore and 68mm outer diameter, crafted from high-quality chrome steel. It features a 25° contact angle and comes in a matched pair for balanced performance.

This sealed bearing handles radial loads up to 3578 lbf and reaches speeds of 41,000 RPM, making it suitable for high-speed applications. Its phenolic cage ensures smooth operation and durability.

The extra-light preload (Class A) reduces friction, while the sealed design keeps lubrication in and contaminants out. Ideal for precision machinery like spindles or CNC equipment where accuracy is key.

Weighing 0.25kg, it’s lightweight yet robust. Compliant with P4A tolerance standards, this bearing is interchangeable with SKF models for easy replacement. Works well in temperatures from -30°C to 110°C.
