For hobbyists seeking less drag in the driveline, the XRAY 940610 ball bearings are an effective choice. Their 6x10x3mm sizing fits many common shafts and diff journals where speed and smoothness matter.
These bearings feature a higher ball count and a reinforced cage to handle heavier loads than basic bearings. The rubber seals help block dirt and moisture so the rolling surfaces stay cleaner for longer.
Side covers can be removed for cleaning and light oiling. A small amount of AeroShell Fluid 12 on the races will keep the bearings turning freely and extend their usable life for both competitive and casual running.
