1. The recommended maximum speed is 1500rpm, 50hz, 1800rpm, 60hz.
2. Providing the recommended power and working temperature are not exceeded. Maximum allowable power ratings are based on a 20% duty cycle. For operation at higher duty cycles or repeated use over any segment of the total travel, working temperature must be monitored and remain less than 85 degree C.
3. Overload capacity of the machine screw jacks is as follows: 10% for dynamic loads, 25% for static loads.
4. The machine screw jacks with single lead screws provide the benefits of a self-locking screw and will hold loads without backdriving in the absence of vibrations. 
5. All machine screw jacks are suitable for intermittent operation providing that the housing temperature including ambient is not lower than -20 degree C. or higher than +85 degree C. Jacton supplied grease in standard units will operate in this range. For higher or lower operating temperature ranges consult Jacton.
