On Application
Notes 1. Static load capacity = 19kN
2. For tensile loads, greater maximum strokes can be accommodated, depending on linear speed.
3. Total weight = basic weight + 2.2 kg (ball screw) per 100 mm stroke.
4. All weights are approximate.
Load Up to 400 kN (40 Te)
Linear Speed Up to 7000 mm/min
Stroke Up to 5000 mm
Efficiency 80% (typical)
Accuracy
Roller Screw Up to within 0.005 mm (5 micron)
Ball Screw Up to within 0.05 mm (50 micron)
Operating Temperature
Normal -10o C → +50o C
Extreme (consult Power Jacks) -30o C → +70o C
Life 10 000 hours typical as standard at full rated load and speed
Enclosure IP55
