Super Precision Angular Contact Ball Bearings 71816 CD/P4DFA

Super Precision Angular Contact Ball Bearings 71816 CD/P4DFA

The 71816 CD/P4DFA is a super precision angular contact ball bearing with an 80mm bore and 100mm outer diameter, crafted from high-quality chrome steel. Its compact 20mm width and 15° contact angle make it ideal for handling combined radial and axial loads.

This matched set of two bearings (DF arrangement) offers extra light preload for smooth, low-friction operation. It supports dynamic radial loads up to 5355 lbf and spins at speeds up to 28,000 RPM.

The open design and phenolic cage ensure durability, while the P4 tolerance class guarantees high precision. It operates in temperatures from -30°C to 110°C and comes pre-lubricated for easy installation.

Perfect for applications like machine tool spindles or high-speed robotics, where precision and reliability are key. Weighing just 0.3kg, it’s a lightweight yet robust solution for demanding environments.
