Bronson G3 bearings are truly exceptional bearings, lightning fast and impact resistant. Built with perfect technology, these bearings thanks to the deeper grooves that are inside the channels make the balls slide much better than other bearings, and also reduce breakages from side impacts. The straight-edge, clutch-free screens fitted to the G3 are not only easy to remove for cleaning but also reduce oil loss and prevent dirt from entering. The micro grooves inside ensure that the lubrication is perfect avoiding the lubricant stationing in front of the balls. The balls are mounted inside a nylon cage that keeps them spaced precisely and always lubricated. The oil is blended with nano-ceramic compounds for wear protection to give you longer lasting bearings and increased speed. Lightweight and smooth, with additives that resist rust, moisture, corrosion and oxidation for extended oil life. Bronson G3s are 100% hand inspected twice. Micro-polished and ultrasonic solvent washed 3 times before final lubrication. Packaged in a nitrogen-filled shrink film that reduces oxidation of metal and oil until ready for transportation.
