Super Precision Angular Contact Ball Bearings 7014 ACETNH/HCP4AL1DBA

Super Precision Angular Contact Ball Bearings 7014 ACETNH/HCP4AL1DBA

The 7014 ACETNH/HCP4AL1DBA is a super precision angular contact ball bearing with a 70mm bore and 110mm outer diameter, crafted from durable chrome steel. It features a 25° contact angle and comes in a matched set of two bearings for balanced performance.

This bearing handles radial loads up to 8190 lbf and spins smoothly at speeds up to 29,000 RPM, thanks to its ceramic balls and phenolic cage. Its extra-light preload ensures minimal friction during operation.

The open design allows for easy lubrication, while the P4A tolerance class guarantees high precision. Ideal for applications like machine tool spindles or high-speed robotics where accuracy is key.

Weighing 1.11kg, it operates reliably in temperatures from -30°C to 110°C. The matched arrangement (DB) provides stability for demanding angular contact loads.
