Super Precision Angular Contact Ball Bearings 71814 ACDGA/HCP2

Super Precision Angular Contact Ball Bearings 71814 ACDGA/HCP2

The 71814 ACDGA/HCP2 is a super precision angular contact ball bearing with a 70mm bore and 90mm outer diameter, crafted from high-quality chrome steel. Its compact 10mm width makes it suitable for tight spaces while maintaining robust performance.

With a 25° contact angle and ceramic balls, it handles radial loads up to 2925 lbf and spins smoothly at speeds up to 28,000 RPM. The phenolic cage ensures durability and reduces friction for efficient operation.

Designed for extra light preload (Class A), this bearing offers precise alignment in demanding applications. It works well in temperatures from -30°C to 110°C and comes pre-lubricated for easy installation.

Ideal for high-speed machinery like spindles or CNC tools, this model is interchangeable with SKF bearings. Weighing just 0.12kg, it’s lightweight yet reliable for precision engineering tasks.
