Ball-Bearing 3x8x4 Steel Sealed - Oil (2)

The XRAY Ball-Bearing 3x8x4 Steel Sealed - Oil is a genuine high-quality precision bearing manufactured for XRAY vehicles, sized 3mm ID x 8mm OD x 4mm thickness. These steel-sealed bearings are degreased and lightly oiled with AeroShell Fluid 12 oil, a treatment chosen for maximum smoothness, long service life, tight tolerances, and consistent performance under load. The steel seal design offers strong protection against dirt and debris intrusion, making this bearing well suited to dusty or abrasive racing conditions where a rubber-sealed bearing might wear faster. Sold as a set of 2, this bearing is used on the XRAY X10 2016-spec off-road buggy platform, and the same bearing size is commonly shared across other compatible driveline and steering assemblies in the XRAY lineup. This is a practical choice for racers performing scheduled drivetrain maintenance, replacing bearings that have become gritty or noisy from wear, or building a complete spares kit ahead of a race weekend. As a genuine XRAY part, it's manufactured to the same tolerances as the bearings originally supplied with XRAY kits, ensuring a proper fit and dependable rolling performance once installed.
