Japanese company Axon have introduced their new X10 ball bearings. The ball races are built using highly precise parts including optimised-size balls to make for the highest possible efficiency. A special coating reduced heat build-up which is further helped by the used of a special bearing oil that greatly reduces drag. The bearings are available in many popular sizes including two 8x4mm and 8x5mm flanged offerings and they come in sets of two.
