Super Precision Angular Contact Ball Bearings 71932 ACDGA/P4AL

Super Precision Angular Contact Ball Bearings 71932 ACDGA/P4AL

The 71932 ACDGA/P4AL is a super precision angular contact ball bearing, measuring 160mm by 220mm by 28mm, crafted from high-quality chrome steel for durability. It handles radial loads up to 27900 lbf and operates smoothly at speeds up to 11000 RPM.

With a 25° contact angle and open design, it offers excellent performance in high-speed applications. The phenolic cage ensures stability, while the extra light preload (Class A) reduces friction for smoother operation.

This bearing comes in matched sets of three, suitable for back-to-back, face-to-face, or tandem arrangements. Ideal for precision machinery like spindles or CNC equipment where accuracy is key.

It works in temperatures from -30°C to 110°C and is interchangeable with SKF bearings, making it a versatile choice for replacements. Weighing 2.7kg, it balances strength and precision.
