Stainless steel deep groove ball bearing and chrome steel deep groove ball bearing with its simple structure are easy to use under largest mass production and wide usage.they will bear moderate axial load sa well as radial load.they can also bear bigger axial load as angular contact deep groove ball bearing do.if the radial clearance is made bigger. Compared with the other types of the same size,its friction will be less and the limit speed becomes larger.Whan the stainless steel thrust ball bearing is not fit because of the high speed.this product can be used to bear prue axial load.
