Development aims

A polymer coating applied to metal is applied to crank washers.
RB100 can improve the reliability (seizure resistance, wear resistance) of washers which is subjected to thrust load and reduce friction.

Development concept

RB100:Solid lubricant + polymer

Solid lubricant: Friction reduction

Polymer: Improving resistance in terms of adhesion to metal improves seizure and wear resistance


seizure resistance

Wear resistance

Friction torque

The superior wear resistance of the RB100 allows the friction-reduction effect and improved wear-resistance effect to be maintained for a long time.

Application example

  • Crankwasher
