Kerk Motion Products assemblies feature reduced friction and extended life

Kerk Motion Products' assemblies, including lead screws, linear rails, spline shafts, slides, guides and actuators, feature the Kerkote TFE coating. The TFE coating reduces friction and extends the life of Kerk's maintenance-free products, which are ideal for motion control applications in a variety of industries.
Unlike hard and so-called “flake-free” coatings that become dry and paste-like and stick to screws, Kerkote TFE is a long-term dry lubricant that transfers to the nut, creating a low friction, protective layer on the nut or bushing without harboring dirt or debris. Requiring none of the maintenance or external lubricant associated with these hard, “flake-free” coatings, Kerkote TFE provides the maximum level of self-lubrication and is more evenly distributed than other lubricants to decrease erratic drag torques and unpredictable wear.  
Kerkote TFE differs from conventional plating and coating because it is soft, and has been shown to extend nut and bushing life as much as ten times when compared with uncoated steel screws and shafts. Over 20 years of experience and repeated testing continue to prove that Kerkote TFE provides longer life for polymer nuts and bushings than any available alternative.
