Super Precision Angular Contact Ball Bearings 71808 ACD/P4DGA

Super Precision Angular Contact Ball Bearings 71808 ACD/P4DGA

The 71808 ACD/P4DGA is a super precision angular contact ball bearing with a 40mm bore and 52mm outer diameter, crafted from high-quality chrome steel. Its compact 14mm width makes it suitable for space-sensitive applications.

With a 25° contact angle, it handles both radial and axial loads efficiently, supporting up to 1667 lbf dynamically. It spins smoothly at speeds up to 56,000 RPM, ideal for high-performance machinery.

The open design and phenolic cage ensure durability and easy maintenance, while the extra-light preload enhances precision. It operates reliably in temperatures from -30°C to 110°C.

This bearing comes in a matched set of two, offering universal mounting options (back-to-back, face-to-face, or tandem). Perfect for precision tools, spindles, or any application requiring tight tolerances and smooth rotation. Weighing just 0.062kg, it’s lightweight yet robust.
