Deep Groove Ball Bearings 61821-zz
The 61821-zz bearing is a deep groove ball bearings with an inner diameter of 105 mm , an outer diameter of 130 mm, a width of 13 mm. It typically uses p0 grade precision tolerances and open zz 2rs type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
Deep Groove Ball Bearings with simple structure ,
are easy to use and maintain. These bearing are
mainly used to support radial load and a certain
amount of axial load. If enlarged the radial internal
clearance of these bearings, the bearings have
the features of the angular contact ball bearings
and can support a heavier axial load. These
bearings have a less frictional resistance and
a high limiting speed , so can operate satisfactorily
under high-speed condition.
