JTD25 Cubic Ball Screw Jack Features 1. Maximum lifting force 20KN, rated dynamic load 17KN. 2. Ball screw diameter 32mm, lead 5mm. Gearbox sizes 130x105x82mm. Center height 41mm, center distance 45mm. Worm shaft diameter 16mm. 3. High gear ratio 1/6 (1 turn input shaft travels 0.83mm), low gear ratio 1/24 (1 turn input shaft travels 0.21mm). 4. Ball screw jack with translating ball screw, rotating ball screw with ball nut, anti-rotation keyed screw (square tube) configurations in upright or inverted mounting orientation. 5. High precision, greater efficiency, higher travel speed, higher duty cycle, lower input torque and long service life. 6. Cranked handle operated, or electric motor, geared motor, reducer driven, or both together. 7. Ball screw travel length is custom made. 8. Ball screw ends include top plate (I), clevis end (II), plain end(III) and threaded end (IV) are available. Custom made spherical hinge, forked head. 9. Individually or multiple jtd25 cubic ball screw jacks lift system arrangements are available. Note:ball screw without self-locking, braking motor, brake mechanism or other locking systems are required when keep the position. When a jtd25 cubic motorized ball screw jack, less power is required than an equivalent size jtc25 cubic acme screw jack.
