Stainless Steel 608 Skateboard Bearing
High-quality stainless steel, wear-resistant and corrosion-resistant, not easy to rust, longer service life.
Chrome Steel 608 Bearing
High hardness, strong wear resistance, excellent compression resistance. It is suitable for players who usually like to stop with flat flower brakes.

Steel seal or rubber seal 
High-quality sealing material, more firmly inlaid with the bearing ring, not easy to fall off, and waterproof, longer bearing life.

Si3n4 ceramic bearings and Zro2 ceramic bearings 
The two balls have extremely small friction, and both have the advantages of high speed, strong hardness, high temperature resistance, strong corrosion resistance, and oil-free self-lubrication. The only difference is that the hardness of white porcelain bearings is slightly lower than that of black porcelain, which is suitable for players who like speed skating, but not suitable for players who stop with flat brakes.

Our Advantages

 

Long service life: The bearing is made of GCR15 or ceramic or stainless steel, which has higher hardness and is anti-rust and anti-corrosion.
Noise reduction by 50%: The contact design between the inner ring and rolling parts of the product is more optimized, and the quality of the steel ball is better combined with the raceway.
The coefficient of friction is reduced by 35%: The raceways of the inner and outer rings of the bearing have been ground many times, the contact surface is smoother, the rotation is more stable, and the rotation time is longer.
Good sealing: the bearing has a dust-proof pad to ensure that no debris enters the inside of the bearing. The groove angle fits perfectly with the dust pad to ensure that the dust pad will not fall off when the bearing rotates at high speed.
