The 7010 CE/HCP4A Ultra-precision angular contact ceramic ball bearings are widely used in high-speed, high-precision applications and situations where there is a risk of shaft current, such as: high-speed machining center spindles, high-speed electric spindles, grinding machine spindles, lathe spindles, ball screw support mechanisms, and medical equipment (high-speed dental drills).

The 7010 CE/HCP4A bearing is a super-precision angular contact ball bearings with an inner diameter of 50 mm , an outer diameter of 80 mm, a width of 16 mm. It typically uses P4A grade precision tolerances and Carbon chromium steel rings, HC = Balls made of bearing grade silicon nitride Si3N4 (hybrid bearing) rolling mlement. Its dynamic radial rated load is approximately 15471 N, its static radial rated load is approximately 10412 N. open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.

The 7010 CE/HCP4A Ultra-precision angular contact ceramic ball bearings are primarily composed of high-precision bearing steel inner and outer rings, silicon nitride ceramic balls, and a cage. The cage is available in ball-guided polyamide (silent series) or brass. Contact angles are available in various specifications, including 15°, 25°, and 40°, with precision grades reaching P4 and above.

Ultra-precision angular contact ceramic ball bearings feature low-density ceramic balls, resulting in low centrifugal force, significantly improved limiting speed, and lower heat generation. The electrical insulation properties of the ceramic material effectively prevent electrolytic corrosion, extending bearing life. The silent series uses ball-guided polyamide cages to reduce vibration and noise, and optimized tolerances ensure more uniform load distribution and superior radial stiffness in bearing groups.
