7210b Bearing 50*90*20mm
The 7210b bearing is a angular ball bearing with an inner diameter of 50 mm , an outer diameter of 90 mm, a width of 20 mm. It typically uses 28600 grade precision tolerances and open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
7210b 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.
