7903 Bearing 17*30*7mm
The 7903 bearing is a angular ball bearing with an inner diameter of 17 mm , an outer diameter of 30 mm, a width of 7 mm. It typically uses 4750 grade precision tolerances and open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
7903 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.
inner diameter:17mm
outer diameter:30mm
thickness:0.017kg
Basic load rating:2800-4750
Speed limeted:30000-40000
Mass:0.017kg
We highly hope to estabish long-term business relationship with you.
