Coating boosts performance of precision components

01 August 2007

Kerk Motion’s motion control products, including its high-performance lead screws, linear rails, spline shafts, slides, guides and actuator assemblies, benefit greatly from the company’s Kerkote TFE coating, designed exclusively for these components and assemblies. Kerkote TFE reduces friction and extends component life. Unlike hard, so-called ‘flake free’ coatings that become dry and paste-like and stick to screws, Kerkote TFE is a long-term dry lubricant that creates a low friction, protective layer on the nut or bushing without harbouring dirt or debris. The coating provides the maximum level of self-lubrication and is more evenly distributed than other lubricants. It differs from conventional plating and coating because it is soft, and has been shown to extend nut and bushing life by as much as ten times when compared with non-coated steel screws and shafts.
