Super Precision Angular Contact Ball Bearings S71916 ACEGA/P4A

Super Precision Angular Contact Ball Bearings S71916 ACEGA/P4A

The S71916 ACEGA/P4A is a super precision angular contact ball bearing with an 80mm bore and 110mm outer diameter, crafted from durable chrome steel. Its compact 16mm width makes it suitable for tight spaces, while the phenolic cage ensures smooth operation.

Designed for angular contact loads, it handles up to 4860 lbf dynamically and spins at speeds up to 28,000 RPM. The sealed design keeps grease in place, reducing maintenance needs.

With a 25° contact angle and P4A tolerance class, it offers high accuracy for demanding applications. The bearing works reliably in temperatures from -30°C to 110°C.

Ideal for precision machinery like spindles or CNC equipment, it’s interchangeable with SKF models. Weighing 0.36kg, it’s lightweight yet robust for its size. Universal matching options allow flexible arrangements.
