Super Precision Angular Contact Ball Bearings S71913 ACEGA/P4A

Super Precision Angular Contact Ball Bearings S71913 ACEGA/P4A

The S71913 ACEGA/P4A is a super precision angular contact ball bearing with a 65mm bore and 90mm outer diameter, crafted from high-quality chrome steel. It features a 25° contact angle and comes sealed for protection, with an extra light preload for smooth operation.

This bearing handles dynamic radial loads up to 3510 lbf and spins at speeds up to 31,000 RPM, making it suitable for high-performance applications. Its phenolic cage ensures durability and reduces friction, while the grease lubrication simplifies maintenance.

Designed for angular contact loads, it works well in temperatures from -30°C to 110°C. The P4A tolerance class guarantees precision, and its universal matching allows for back-to-back, face-to-face, or tandem arrangements.

Ideal for precision machinery like spindles or CNC equipment, this bearing is interchangeable with SKF models. Weighing just 0.2kg, it’s lightweight yet robust for its size.
