Super Precision Angular Contact Ball Bearings S71907 ACB/P4ADBB

Super Precision Angular Contact Ball Bearings S71907 ACB/P4ADBB

The S71907 ACB/P4ADBB is a super precision angular contact ball bearing with a 35mm bore and 55mm outer diameter, crafted from durable chrome steel. It handles radial loads up to 1755 lbf and reaches speeds of 56,000 RPM, making it suitable for high-performance applications.

Its sealed design keeps grease in and contaminants out, while the phenolic cage ensures smooth operation. The 25° contact angle and light preload (Class B) provide excellent stability for paired bearings in a back-to-back arrangement.

This bearing is ideal for precision machinery like CNC spindles or high-speed motors, where accuracy and reliability are key. It operates smoothly in temperatures from -30°C to 110°C.

Weighing just 0.16kg, it’s lightweight yet robust. The P4A tolerance class ensures top-tier precision, and it’s interchangeable with SKF bearings for easy replacements.
