The Bronson Speed Co. Next Generation Bearings have 7 steel ball bearing with a steel casing. The deep groove raceways reduce impact damage and maintain speed. Non-contact rubber shields protect against grime, reduces oil leaks, and allows for easy cleaning. Microscopic groove raceways are self-smoothing for improved lubrication and spin. The max impact cage design is constructed with non-distorted glass filled nylon for strength and evenly spaced ball bearings.
The ball cage sockets surfaces are engineered to hold oil for lubrication. Built with Bronson's "Balls Out Technology", the balls-out cage-in orientation reduces shield and cage contact for increased speed. A special blend high speed ceramic oil increases durability, reduces rust, and increases speed.
Each set of Bronson bearings are hand inspected twice, micro polished, ultrasonic solvent washed 3 times prior to lubrication, and packaged in nitrogen filled shrink wrap to reduce oxidation during shipping.
