7904 Bearing 20*37*9mm

7904 angular contact ball bearings.Single row angular contact ball bearings can withstand axial load in one direction, the radial load, will cause additional axial force. And the only limit shaft or housing in a direction of axial displacement. Angular contact ball bearing contact angle of 40 degrees, so you can bear large axial load. Angular contact ball bearing non-separation type design, inner and outer rings on both sides of the shoulder uneven. In order to improve the bearing load capacity, which would lower side of the shoulder machined, so that the ball bearings can be put more.
