Deep groove ball bearing 627 ,627z skate bearing are simple in design, non-separable, suitable for high and even very high speeds and are robust in operation, requiring little maintenance.Deep-groove bearings have higher load ratings for their size than shallow-groove , but are also less tolerant of misalignment of the inner and outer races.
Skateboard bearings are not as sophisticated as those of yo-yo. Because there are eight bearings and four middle locks on one plate, it is best to replace the eight bearings, no matter which axis first explodes.
The high temperature generated by the rotation of the bearing when using the skateboard will closely adhere the rubber of the wheel to the bearing wall, which is inconvenient when changing the wheel or changing the bearing. Therefore, it is necessary to remove the bearing from the wheel and install it. This is to avoid trouble and also to clean the bearing.
