Super Precision Angular Contact Ball Bearings 7014 ACE/HCP4AH1DBA

Super Precision Angular Contact Ball Bearings 7014 ACE/HCP4AH1DBA

The 7014 ACE/HCP4AH1DBA is a super precision angular contact ball bearing with a 70mm bore and 110mm outer diameter, crafted from high-quality chrome steel. It features a 25° contact angle and comes in a matched pair (DB arrangement) for balanced performance.

This bearing handles radial loads up to 8190 lbf and reaches speeds of 29000 RPM, thanks to its ceramic balls and phenolic cage. The extra light preload ensures smooth operation with minimal friction.

Its open design allows for easy lubrication, while the P4A tolerance class guarantees exceptional accuracy. Ideal for high-speed applications like machine tool spindles or precision equipment.

Weighing 1.11kg, it operates reliably in temperatures from -30°C to 110°C. The matched pair setup provides stability for demanding angular contact load scenarios.

The 7014 ACE/HCP4AH1DBA is interchangeable with SKF bearings, offering a trusted alternative. Its robust construction and precision make it suitable for industrial and technical uses where accuracy is key.
