Ball-Bearing 5x8x2.5 Rubber Sealed - Oil (2)

The XRAY Ball-Bearing 5x8x2.5 Rubber Sealed - Oil is a genuine high-speed precision bearing manufactured specifically for XRAY vehicles, sized 5mm ID x 8mm OD x 2.5mm thickness. Each bearing features special rubber covers that keep out dirt and debris while remaining removable for servicing, and the bearings are degreased and lightly oiled with AeroShell Fluid 12 oil to maximize smoothness and minimize rolling resistance. Compared to standard bearings, these are built with an increased ball count and size for improved load resilience, making them a strong fit for the demands of competitive racing. Sold as a set of 2, this compact bearing size is used across multiple XRAY chassis platforms wherever a low-profile, smooth-rolling bearing is required in the drivetrain or steering assembly. Because the side covers are removable, this bearing can be periodically cleaned and re-oiled rather than replaced outright, helping extend its usable life between rebuilds. This is a solid pickup for racers performing routine maintenance, replacing worn or contaminated bearings, or upgrading from stock hardware for smoother, more consistent rolling performance. A genuine XRAY component built for dependable, race-ready results.
