Lead screws are a component part of the screw-nut transmission, and are used to transform rotating movement into forward movement.
To provide smooth moving, increasing load-carrying capacity, and reducing wear of the components, it is necessary to use lubricating materials even in case if some lubricating substances are integrated into polymer nut structure.
Oils and greases attract dust and other small particles, and thus contribute to abrasive wear of the parts, they also need frequent refreshing, and lose their operability in aggressive media.
The most effective way to extend service lifetime and function reliability of the lead screws is use of MODENGY 1014 anti-friction solid-film coating on the stage of producing the parts. It is made on basis of the solid lubricating substances such as polytetrafluoroethylene and molybdenum disulfide.
MODENGY coating provides corrosion protection for lead screws, impact from the chemically aggressive media, and other adverse environmental factors, from scuffing forming, and other damages of the turns, it prevents stick-slip motion, reduces friction and wear of the parts in process of operating.
This coating retains operability at -75 °С to +255 °С, in dusted environment, and chemically aggressive media.
MODENGY 1014 is applied out of a spraying gun, and polymerizes at heating in a kiln. After curing, a steady layer of the product needs no refreshing for the entire service term of the screw gear.
Use of this anti-friction solid-film coating enables to achieve the best operational properties of the lead screws including corrosion resistance, load-lifting capacity, durability, and reliability.
