Raw Steel Material requirement is higher than required (GB/t18254) requirement in the aspects of chemical element, nonmetallic inclusion, carbide inhomogeneity and etc.
All Hub Assemblies go through a vacuum vulcanization process to enhance the structural integrity of the seal and rubber components.
In order to increase longevity and resist abrasion, GSP's ball bearings are space precisely to the appropriate clearance for smooth rotation.
To ensure a smooth surface, free from defects, burrs, and cracks, all bearing housings are manufactured with polyamides for added impact toughness and age resistance.
Hub Assemblies are engineered with Silent Ride Technology (SRT) to ensure a comfortable and quiet ride. Strict engineering tolerances in conjunction with the highest quality bearing components are integral to this superior design.
