Abstract
Roller follower assemblies generally reduce frictional losses and wear associated with operating fuel injectors using a cam. Oil helps to reduce wear, but may not remove small particles. Buildup of these small particles may prevent a roller of the roller follower assembly from rotating about an axle pin. In the present invention, a hard coating is disposed between the axle pin and the roller to reduce rolling friction and buildup of small particles.
