The XRAY 940513 bearings are a 5x12x4mm pair designed to reduce drivetrain drag and provide reliable rolling performance across a range of RC vehicles. They are compact, serviceable, and ready for track or trail use.
A rubber seal helps keep contaminants away from the race and balls, while a light factory lubrication ensures smooth initial running. The cage holds more and slightly larger balls to better handle impact and sustained loads.
These bearings feature removable side covers for easy cleaning and relubrication, letting you maintain consistent performance and extend the effective life of the parts.
