* Maximum temperature for continuous exposure. Higher surge temperatures may be
permissible but should be validated in the actual end use by the OEM.
Low temperature limits are -15°C or lower. Consult Danaher Motion for specifics.
PTFE coating is a dry film which creates a lubrication barrier between a metal substrate and a polymer bushing or lead nut. It can in some cases eliminate the need for an additional gel type lubricant which must be reapplied. It is well suited for use with our SuperNut line of plastic nuts and stainless steel lead screws. Lubrication maintenance intervals can be eliminated and the coating does not attract particulate like a gel lubricant. Gel lubricants can provide lower friction coefficients than dry film lubricants but must be maintained to prevent performance degradation. PTFE coating provides an attractive and clean* alternative to gels and oils.
| Type: | Bonded Solid Film Lubricant |
|---|---|
| Purpose: | Increased Lubricity, Decreased Friction & Wear |
| Appearance: | Black Coating |
| Thickness: | Approx. 13 – 25 micron |
| Active Lubricant: | Polytetrafluroethylene |
| Friction Coefficient: | 0,06 to 0,12 |
| Temperature Operating Range: | -250° to 290° C |
| Resistance to Acids: | Excellent |
| Resistance to Bases: | Very Good |
| Resistance to Solvents: | Excellent |
* Some particulate will be generated as a result of wear between nut and screw.
Screw may begin to show signs of “polishing” over time. This does not necessarily indicate failure.
