RC racers who want tighter drivetrain response will appreciate the XRAY 941318 high-speed ball bearings. Made to suit the XB8/18 and XB8E/18 platforms, these 13x19x4mm bearings deliver consistent rotation and reliable service under racing conditions.
The rubber seal shields the internal races from grit and moisture, helping to prevent premature wear. The high-speed build reduces friction so the drivetrain runs more efficiently during long heats.
Precisely engineered to fit XB8/18 and XB8E/18 mounting points, these bearings help smooth steering inputs and support crisper acceleration by cutting rolling resistance.
