DHK double row angular contact ball roller has two kinds, one is straight diameter 3057... And 3067... Series, another is the arc surface outer diameter of 3058... And 3068... Series, 3057... And 3058... The interior design of the series is the same as the 32... Series double row angular contact ball bearings; 3067... And 3068... The interior design of the series is the same as 33... Series double row angular contact ball bearings.

The contact Angle of DHK double-row angular contact ball bearing roller is 25°, and the radius of the circular arc surface outer diameter roller is R=400mm.

Most of these bearings are dust-proof covers on both sides (suffix.2z) and contact sealing rings on both sides (suffix.2RSR).
DHK double row angular contact ball roller is made of plastic cage.

DHK double row angular contact ball roller uses ordinary tolerance, for the circular surface outer diameter of the roller diameter tolerance is twice the standard value.
