Super Precision Angular Contact Ball Bearings S71914 ACB/P4ADT

Super Precision Angular Contact Ball Bearings S71914 ACB/P4ADT

The S71914 ACB/P4ADT is a super precision angular contact ball bearing with a 70mm bore and 100mm outer diameter, measuring 32mm in width. Made from durable chrome steel, it’s designed for high-speed operations up to 22,000 RPM.

With a 25° contact angle and sealed design, it handles both radial and angular loads efficiently. The phenolic cage ensures smooth performance, while the matched pair setup (DT arrangement) provides stability under preload conditions.

This bearing is ideal for precision applications like machine tool spindles or high-speed robotics. It’s interchangeable with SKF bearings, making replacements straightforward.

Weighing 0.72kg, it operates smoothly in temperatures from -30°C to 110°C. Compliant with P4A tolerance standards, it’s a reliable choice for demanding environments.
