Damping Grease

 

Designers and manufacturers have used damping greases for more than 50 years as an economical way to build fine tolerances into their products. The “velvet feel” and virtually silent operation of the focusing mechanisms on microscopes, zoom lenses on 35mm cameras, and other optical instruments, and the fact that the lens doesn’t continue to “coast” when the mechanism is stopped, are all the results of a damping grease applied to the focusing threads. Damping greases are also widely used for electronic controls such as potentiometers, where they ensure smooth, quiet, controlled motion, and make possible very precise settings, very cost-effectively, that could not otherwise be made my hand. They are also found in gear trains and gear motors, appliance controls, electric switch mechanisms, laser controls, television tuners, and in many automotive, hand-actuated or instrument panel control applications, where “quality feel” usually indicates the presence of a damping grease.

When selecting a damping grease - objective and subjective criteria apply. Objectively, damping greases must retain their damping qualities throughout the temperature range of the application, so careful attention should be paid to the temperature range of each grease. More subjectively, damping greases are selected for the “feel” the designer wants to achieve. Generally, the more delicate the device, the lighter the grease. Damping greases come in standard grades, from extra light to very heavy, and Nye can formulate them to meet any gradation in between. Importantly, when determining a grade and how much grease to apply to a device, carefully consider the amount of torque available at the lowest operating temperature, when the grease is most viscous.

Low Torque/Low Temp Damping Greases

Temp Range (°C) Grade  Typical Applications
Nyogel 774VL -50 to 120 Ultra Light Automotive glove box latches 
Nyogel 774L -40 to 120 Very Light Automotive HVAC controls & seat track systems
Nyogel 774 -30 to 120 Light Automotive power window switches
Nyogel 774H -20 to 120 Medium Steering column & pen screw mechanisms
Nyogel 774VH -10 to 120 Heavy Camera focusing & motorbike drive by wire twist throttle

 

Shear Stable Damping Greases

Temp Range (°C) Grade  Typical Applications
Fluorocarbon Gel 868VL -45 to 125 Ultra Light Document and photo printer keys
Fluorocarbon Gel 868L -40 to 125 Very Light Dimmer switches & starter motor solenoids
Fluorocarbon Gel 868 -40 to 125 Light Manual car seat controls & fridge temp controls
Fluorocarbon Gel 868H -30 to 125 Medium Stereo volume controls, surveying equipment
Fluorocarbon Gel 868VH -20 to 125 Heavy Zoom focusing and medical devices

 

Heavy Duty Damping Greases

Temp Range (°C) Grade  Typical Applications
PG-44A +20 to 120 Extra Heavy

Binocular focusing heads/systems, self build light aircraft nose wheel, assembly aid

PG-44A-LS +10 to 120 Very Heavy Similar applications as PG-44A. This 'LS' variant is a less viscous version of PG-44A. Has been found by customers to be a suitable replacement for Rocol 0868 Kilopise grease.


Should you choose one of the 774 or the 868 damping greases? Both ranges perform similar functions but utilise different chemistry to achieve their damping goal.

The 868 range is thickened with PTFE which is normally white in colour, hence the 868 range is white in appearance. The 774 range is either a tan or blue colour but will appear translucent in thin layers and is less visable on dark surfaces, if visability is an issue. The 868 products have a better shear stability and our experience is that they are better suited to metal on metal applications or applications where the grease will experience prolonged periods of use. 774 greases can be better suited to plastic applications and have a lower price point.

PG-44A is probably the heaviest damping grease that we supply. It is not recommended that PG-44A be purchased in a tube as it is hard to dispense due to the stiffness of the grease. PG-44A can be heated up to aid application and is often used as an assembly aid. Example: PG-44A is a popular solution to light aircraft enthusiasts to combat front nose wheel shimmy and the grease is also used to for high level damping tasks such as binocular focusing systems.

Material compatibility problems with the damping greases is not common but we recommend that you consult the Nye compatibility chart that is within the Engineering_Reference_Chart.pdf. If still concerned consider a compatibility test - see the relevant question on the FAQ page for further information.
