skate bearing size 7*22*7mm high speed ceramic bearings for roller skates
skate bearing size 627 7*22*7mm as an important machine parts, metal bearings because of its unmatched superior performance, high temperature, super-strength materials in the new world dominate.

1. Since the ceramic is almost afraid of corrosion, so the ceramic rolling bearing suitable for operation under harsh conditions full of corrosive media.
2. Since the ceramic rolling the ball lower density than steel, more weight is much lighter, so the rotation of the outer ring when the centrifugal effect can be reduced by 40%, thus greatly extended service life.
3. ceramic expansion and contraction than steel is small, and therefore when the bearing clearance must be allowed to work in bearing temperature changes more severe environment.
4. As ceramic high modulus of elasticity than steel, not easy to deform under stress, and therefore help to improve the speed and achieve high accuracy.
