Screw Jack, Worm Gear Screw Jacks - JACTON Industry

1 ton, 2 ton, 3 ton, 5 ton, 10 ton precision gear lifts worm gear drive, precision screw jack mechanical actuators, precision linear jack screw for precision straightener in USA. Precision straightener is designed so that the entry and exit feed rolls, along with all of the lower straightener rolls, are driven together. This is accomplished with a huge servo motor, helical-bevel reducer and gear train. All upper rolls will lift for pilot registration using a heavy-duty pneumatic or hydraulic system, a much heavier-duty design than the pilot-release systems available on pull-through straighteners, according to company officials. A benefit of the design is that the precision straightener rolls, while able to lift for pilot registration, are still independently adjusted. This gives them greater depth penetration and flexibility when compared to bank-adjusted and pull-through straighteners. The system can be combined with either a cradle or a reel and coil car for a numb
