In order to make it have good dustproof effect, the other side of inner ring 3 offers air inlet 15, and inner ring 3 is close to first
Groove 7, both sides insertion air curtain band 17 is installed, and several air outlets 18 are equidistantly offered on air curtain band 17, inner ring 3 it is interior
Portion is equipped with air hose 16, and one end of air hose 16 is connect with air inlet 15, and the other end is connect with air outlet 18.
In order to ensure that fixed stability, the inner wall correspondence of inner ring 3 offer card slot 4.
In order to which ball 5 can be completely fitted, the outer diameter of ball 5 is equal to the first ball limiting slot 8 and the second ball limiting slot
11 opposite ends sum of the distance.
In order to reduce friction, energy loss, the inner wall and rolling of the first ball limiting slot 8 and the second ball limiting slot 11 are reduced
Polishing treatment is passed through on the surface of pearl 5.
In order to promote the service life of ball 5, ball 5 is a kind of high-carbon-chromium bearing steel material members.
For the normal rotation of ball 5, the diameter of the first ball limiting slot 8 is equal to the diameter of the second ball limiting slot 11.
