Low Friction Linings

Versiv Low Friction Linings (LFL) are used in any application where reducing friction and wear is important for improving performance and extending the life of equipment.

Overview
LFLs are a composite of fluoropolymer and reinforcing fabric required in components such as electromagnetic solenoids, actuators, sliding roof systems, and printer fuser roll pressure pads. 
In addition, our linings make devices more energy efficient by reducing the level of abrasion. Their use also means more consistent movement forwards and backward with minimum hysteresis or "slip-stick" effects. In specific applications, it minimizes the noise level generated by movement and performs consistently even at temperatures up to 200°C or higher throughout the device's lifetime.
Low friction linings can replace messy greases, oils or lubricants that wear out or need frequent "topping-up". They can also replace metallic coatings, such as nickel or chrome, that are expensive and difficult to get in consistent quality.
Benefits of Versiv Low Friction Linings
Low hysteresis
Hysteresis testing of different Versiv Low Friction Linings (LFL) confirm that the force requirement is low and very stable and remains in the same range throughout the design lifetime of the solenoid. In addition, there is the benefit of no “stick-slip” effect. 
Reduced power requirements:
Due to the smaller air gap and low friction properties of Versiv LFL versus a stainless-steel tube, the energy consumed by the solenoid can be reduced by over 60%. 
Consistent wear and low friction:
Versiv LFL have very consistent wear and low friction properties over their lifetime with little change in performance even after wear testing up to 10 million cycles. The lubricious and durable surface against the moving armature eliminates the risk of frictional “pick-up” or metallic contamination. They have been tested with contaminated “dirty” hydraulic and transmission oils and still performed satisfactorily.  
Increased force:
The available force and load capability can be increased by up to 65% with a Versiv LFL, thus enabling greater design flexibility.
Decreased thermal expansion: 
Stable at temperatures from -180°C to +260°C. Analysis of coefficients of thermal expansion of Versiv LFL indicates values of 50% to 60% less than cold rolled steel or stainless steel respectively for a similar temperature range. 
Industries
Back of a car.
Automotive industry: 
Low friction linings are used in brake systems, double clutches, other transmission systems, and roof blind sliding systems to reduce wear and hysteresis to improve performance. 
Industrial machinery: 
Low friction linings are used in bearings, gears, and other mechanical components to reduce friction and improve efficiency. 
Printers:
Low friction linings are used as a bearing type material serving to facilitate optimized movement of paper through the machine during the printing process.  
Electromagnetic solenoid applications
Versiv LFL offers improved design flexibility with more options for highly effective and economical designs due to an overall reduction in space and weight.  
Our analysis indicates the following potential savings, in particular in the automotive applications: 67% Reduction in Coil Mass, 28% Reduction in Solenoid Mass, and 32% Reduction in Solenoid Package Volume.
We will work with you to help produce vehicles and systems that meet higher levels of fuel efficiency, increased life cycle, lower cost, and heightened performance. The optimization of hysteresis and low friction properties of Versiv LFL in EM solenoids have enabled improved transmission responsiveness and driver comfort which are important benefits in the increasingly demanding automotive market.
