Super Precision Angular Contact Ball Bearings 7019 CD/HCP4A

Super Precision Angular Contact Ball Bearings 7019 CD/HCP4A

The 7019 CD/HCP4A is a super precision angular contact ball bearing with a 95mm bore and 145mm outer diameter, crafted from high-quality chrome steel. It handles radial loads up to 18428 lbf and operates smoothly at speeds up to 17000 RPM.

Its 15° contact angle and ceramic balls reduce friction, while the phenolic cage ensures quiet, efficient performance. The bearing comes pre-lubricated and works in temperatures from -30°C to 110°C.

This open-design bearing is ideal for high-speed applications like machine tool spindles or precision equipment. Its P4 tolerance class (ABEC-7) guarantees exceptional accuracy.

Weighing 1kg, it’s robust yet manageable for its size. Interchangeable with SKF bearings, it’s a reliable choice for replacements or upgrades.
