Ball-Bearing 6x13x5 Rubber Sealed - Oil (2)

The XRAY Ball-Bearing 6x13x5 Rubber Sealed - Oil is a genuine high-speed precision bearing manufactured specifically for XRAY vehicles, sized 6mm ID x 13mm OD x 5mm thickness. Each bearing features special rubber covers that seal out dirt and debris while allowing for easy removal during maintenance, and the bearings are degreased and lightly oiled with AeroShell Fluid 12 oil for maximum smoothness and reduced rolling resistance. Compared to standard bearings, these are built with an increased ball count and size for greater load resilience, making them well suited to the higher stresses found in competition use. Sold as a set of 2, this bearing is used on the XRAY NT1 PRO nitro touring platform, though the same bearing size is shared across other compatible XRAY models. Because the side covers are removable, racers can periodically clean and re-oil these bearings rather than replacing them outright, extending their service life. This is an ideal pickup for owners performing routine drivetrain maintenance, replacing worn or contaminated bearings, or upgrading from stock bearings for smoother, more efficient rolling performance. A genuine XRAY component built for consistent, race-ready reliability.
