SuperSpeed's SB208-50CH 50x80mm ceramic hybrid bearings are custom manufactured with our unique ultra-low friction seals and low viscosity oil lubricant. Our SB208 bearings utilize the standard spherical insert configuration for 50mm bearings, with an extended shoulder on one side for the utilization of set screws. But we utilize Ball Point type set screws, originally developed by NTN to reduce or eliminate axle damage and distortion that standard knurled or cup-style set screws cause, while lasting over 7 times longer.
All of our bearings are custom manufactured exclusively for SuperSpeed™ Racing. We start with the highest quality ceramic hybrid bearing components, including 52100 chrome steel deep groove rings, solid silicon hydride (Si3N4) polished balls and low friction polyamide cages, manufactured to C3 clearance and P6 precision. Then we go further than any other manufacturer, utilizing unique ultra-low friction, -contact seals and low viscosity oil lubricant, eliminating up 90% of the friction of most other ceramic bearings. (Note that SuperSpeed™ bearings should be lubricated before the first use, re-lubed frequently and cleaned occasionally, depending on conditions of use, to offer the lowest friction and longest life possible. (See our Tech Tip Lubricating Your SuperSpeed™ Bearings for more details on caring for your bearings.))
Dimensions: 50x80x34mm (including extended shoulder; bearing body is 18mm wide)
