While lubrication is probably the last thing patients or health care professionals think about, far upstream the engineer who designs mechanical and electromechanical medical devices has to think about it. Otherwise, performance — perhaps even a medical procedure — could be compromised. Nye is your partner in selecting the right lubricant for moving parts in medical and dental instruments. More importantly, it’s about seeing the lubricant not merely as an add-on near the end of the design cycle, but as a critical design material. Carefully selected, lubricants do much more than reduce friction and wear. They can lengthen the life of the device, broaden the temperature range at which it operates, reduce unwanted noise, control free motion, impart a clinically appropriate feel, provide an environmental seal, cut design and production costs — and even reduce warranty claims. In short, lubricants can add value even to breakthroughs in medical technology.

Synthetic Lubricants for Medical DevicesWhile lubrication is probably the last thing patients or health care professionals think about, far upstream the engineer who designs mechanical and electromechanical medical devices has to think about it. Otherwise, performance — perhaps even a medical procedure — could be compromised.
Damping Grease BrochureThis brochure is a basic introduction to Nye's Damping Grease. It gives real-world examples of how damping grease is used across a variety of industries. Covered are the material, its history, and how damping grease reduces noise and wear and controls the "feel" of mechanical devices.
Lubricants for Stationary Separable Electrical ConnectorsThe advantages of lubricating electrical connectors. Reduces friction, eases mating. A thin film of lubricant can reduce mating force by as much as 80 percent, an important factor in connector assembly. For electronic connectors with dozens or even hundreds of pins, or for automotive connectors that are in hard-to-reach places, a low insertion force makes assembly more efficient and ensures solid connections.
Damping GreasesA damping grease is a cost-efficient way to control free motion, achieve a “quality” feel, reduce noise, and enable fine tuning by hand in most any mechanical and electromechanical device.
Synthetic Food-Grade LubricantsWhile many mineral-oil-based products meet the NSF International’s food-grade requirements, they often do not measure up to the more demanding temperature and load requirements of modern food, beverage, and pharmaceutical processing equipment. Compared to mineral-oil lubricants, synthetics tolerate both lower and higher temperatures, offer improved antiwear properties, extend lubrication intervals, and lengthen the service life of moving parts. Like mineral oils, synthetic foodgrade lubricants are nontoxic, odorless, colorless, and tasteless.

*Caution: These compatibility ratings are intended to be guidelines for design engineers when selecting lubricants. Under high mechanical stress, high temperature, poor plastic/elastomer quality, or any combination of these conditions, compatibility can be compromised. Any synthetic lubricant used with a plastic or elastomeric component should be tested to ensure compatibility in a specific application.
