9. The high strength bearing of claim 8, wherein the moving assembly further comprises a push plate slidably engaged with the groove and movably connected with the guide post, the push plate and the groove are adapted in shape and size.
10. The use method of the high-strength bearing is characterized by comprising the following steps:
s1, the inner ring is connected with an external rotating shaft in a matched mode, the rotating shaft drives the inner ring, the retainer and the air guide assembly to synchronously rotate when rotating, the retainer drives the balls to rotate along the inner wall of the outer ring, and the balls can also automatically rotate;
s2, the coating roller rotates along with the ball, on one hand, graphite of the material supplementing assembly is coated on the surface of the ball, and on the other hand, the ball is added with another self-rotation track through the first belt pulley and the adjusting assembly;
and S3, when the air guide assembly corresponds to one of the round holes, the air is discharged from the lower round hole through the upper round hole and the inner part of the coating roller.
