Swain Tech Coatings’ PPM™ solid film lubricant is a thin, tough coating applied to bearing shells to reduce friction and improve the wear life of both the bearing shells and journals under normal operating conditions. However, it is when operating conditions are less than ideal that PPM™ really goes to work. If there is a cold start, oil starvation or any other situation where the primary lubrication is less than ideal, PPM™ will provide a solid film of lubrication to prevent a catastrophic failure.
