PT Link Systems , Australian national distributor for Duff Norton based in Melbourne, offer the new SCN series SuperCylinders, which are suitable for critical applications demanding high capacities and high speeds. The new SCN electric cylinder series SuperCylinders are already being used in the mining, steel, defence, materials handling, communication, food and other industries, they replace both electric and hydraulic cylinders.
Following are the features of the SCN electric cylinder series SuperCylinders:
- Speeds up to 379.5in/min (160.7mm/sec)
- Capacities up to 25 tonnes
- Standard strokes up to 13 feet (3.962m)
- Helical and helical bevel gearing
- Continuous duty ratings
- Optional fitment of DIP and increased safety motors
- Low power requirements
- Trunnion mounting
The Duff Norton SCN electric cylinder Series SuperCylinders use the combination of a precision guided translating tube system, coupled to a motor and reducer through a trunnion housing. Three basic configurations of SuperCylinders available are offset, parallel and right angle.
The ground and chrome plated translating tube sliding in polymeric bearings produces good resistance to buckling and wear. This guided tube assembly lets SuperCylinders achieve greater stroke lengths in compressive loading than is possible with conventional double clevis mounted mechanical actuators.
Enclosure of the screw by the tube system shields it from environmental contaminants and retains lubricants, requiring less maintenance and allowing longer service. Electric cylinder SuperCylinders use hydraulic cylinder grade wiper seals to exclude dirt from the screw area. The modular design concept employed by Duff Norton electric cylinder allows an unlimited choice of gear ratios and configurations enabling precise tailoring of actuators speeds, capacities, motor types and life requirements.
