Super Precision Angular Contact Ball Bearings 71905 ACEGA/P4A

Super Precision Angular Contact Ball Bearings 71905 ACEGA/P4A

The 71905 ACEGA/P4A is a super precision angular contact ball bearing with a 25mm bore and 42mm outer diameter, crafted from durable chrome steel. Its compact 9mm width makes it suitable for tight spaces while maintaining high performance.

With a 25° contact angle, it handles both radial and axial loads efficiently, supporting dynamic radial loads up to 1141 lbf. It spins smoothly at speeds up to 100,500 RPM, ideal for high-speed applications.

The open design and phenolic cage ensure low friction and easy maintenance. It operates reliably in temperatures from -30°C to 110°C and comes pre-lubricated for immediate use.

This bearing is interchangeable with SKF models and can be paired in back-to-back, face-to-face, or tandem arrangements. Perfect for precision machinery like spindles or dental tools where accuracy and speed are crucial.

Weighing just 0.04kg, it’s lightweight yet robust, meeting P4A tolerance standards for exceptional precision.
