Super Precision Angular Contact Ball Bearings S71915 ACB/P4ADT

Super Precision Angular Contact Ball Bearings S71915 ACB/P4ADT

The S71915 ACB/P4ADT is a super precision angular contact ball bearing with a 75mm bore and 105mm outer diameter, crafted from durable chrome steel. It handles radial loads up to 4860 lbf and operates smoothly at high speeds up to 28,000 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 << DT) provide excellent stability for angular loads. This bearing is ideal for precision applications like machine tool spindles or high-speed motors, where accuracy and reliability are key. It works well in temperatures from -30°C to 110°C and comes pre-lubricated for easy installation. Weighing 0.76kg, it’s a robust yet manageable choice for demanding setups. Compliant with P4A tolerance standards, it’s interchangeable with SKF bearings for convenient replacements.
