Built for Kyosho RC drivetrain systems, this one-way bearing grease is designed to reduce friction and wear in one-way bearing assemblies for smoother engagement and longer service life. It helps maintain consistent one-way operation by preventing slippage and protecting internal components from heat and mechanical stress. The specialized formulation improves efficiency in high-speed applications while extending bearing durability under repeated load. It is intended for use during maintenance and assembly of compatible Kyosho engines and drivetrain systems where one-way bearings are used.
