7206CD/HCP4A Angular Contact Ball Bearing Size 30x62x16mm Super Precision 7206 CD/HCP4A

7206CD/HCP4A is a high-precision angular contact ball bearing engineered for high-speed, high-rigidity applications. The "CD" designation indicates a 15° contact angle, optimizing it for radial loads and moderate axial loads (single direction), while the "HCP4A" precision grade ensures ultra-low runout and tight dimensional tolerance—ideal for precision transmission systems. Crafted from high-quality bearing steel, its raceways and balls undergo precision grinding and superfinishing to minimize friction and vibration, enabling stable operation at extreme rotational speeds. The bearing’s robust structure and optimized internal design enhance load distribution, extending service life in demanding precision machinery scenarios.

Angular contact ball bearing can bear radial load and axial load at the same time. The contact angle is higher, the axial load capacity is higher, the high precision and high speed bearing usually take 15 degree contact angle.

Single row angular contact ball bearings only bear a direction of the axial load in the bearing radial load will cause additional axial force. And only limit shaft or shell in a direction of the axial displacement. Angular contact ball bearing contact angle is 40 degrees, so can bear great axial load.
