Lead screws with TFE coating

Kerk Motion Products' lead screw, linear rail, spline shaft and ScrewRail actuator assemblies are available with Kerkote TFE coating. The coating reduces friction and extends the life of Kerk's assemblies, which are suitable for motion control applications in a variety of industries.

The coating is claimed to be more evenly distributed than other lubricants, decreasing erratic drag torques and unpredictable wear. Designed for Kerk's components and assemblies, the coating provides the maximum level of self-lubrication, requiring no additional external lubrication or maintenance.

Since it is a dry lubricant, the coating will not become dry and paste-like, and does not attract dirt or debris. Kerkote differs from conventional plating and coating because it is soft, making it suitable for extending the life of polymer nuts and bushings.
