Bionic SWISS Bearings feature titanium ball bearings and utilize shields to protect the internal parts of the bearing against contamination by dust, and liquid. The shields help contain the lubricant in the bearing, are fixed to the outer ring and have a non-rubbing seal to the inner ring. Delrin™ cages with extra deep grooves for increased longevity and low maintenance.

These high-performance skate bearings require no break-in period.
Bionic SWISS features deeper grooves, double honed races for smoother, faster and longer lasting bearings and cages made of Delrin™, a DuPont product. Delrin™ acetal homopolymer combines lubricity and wear resistance with the stiffness and strength needed in parts designed to replace metal.

• Chemical resistance to fuels and solvents
• High fatigue resistance
• ESD safe and static dissipative
• High strength and stiffness properties
• Very low water absorption

Another important feature is the materials of which the inner and outer rings as well as the balls are made of. Bionic uses Stainless Steel rings and titanium balls for great corrosion resistance and hardened capabilities that improve speed and longevity. Key elements to these materials is the process of heat treating.

All Bionic SWISS Bearings are packaged in speed oil so that they are ready to use right out of the package. No need to clean them in order to achieve optimum speeds, nor is there any break-in time.
