Super Precision Angular Contact Ball Bearings 71826 CDGA/HCP4

Super Precision Angular Contact Ball Bearings 71826 CDGA/HCP4

The 71826 CDGA/HCP4 is a super precision angular contact ball bearing with a 130mm bore and 165mm outer diameter, crafted from high-quality chrome steel. It handles radial loads up to 8775 lbf and operates smoothly at speeds up to 11000 RPM.

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

Designed for precision applications, it’s ideal for machine tools or high-speed spindles where accuracy is key. The P4 tolerance class guarantees reliable performance in demanding conditions.

Weighing 0.7kg, it’s part of a matched set of four bearings, suitable for back-to-back, face-to-face, or tandem arrangements. Interchangeable with SKF models, it offers flexibility for replacements.
