Ball screw jack JTD50

rotating screwtranslating screwcubic

* Maximum static load capacities 50 kN (5000kg). * High precision ball screw sizes 40x10, 40x20. * Two gear ratios: high ratio 7:1, slow ratio 28:1, for high and slow linear speeds (up to 4.2 m/min) * Custom stroke length of ball screw, maximum stroke 3000 mm in compression load, 4000 mm in tension load. * Basic designs: Translating screw, Anti-rotation screw, and Rotating screw. * Upright or Inverted mounting. Available in tension or compression loads. * Ball screw end fittings: top plate, clevis end, threaded end, plain end, fork head and rod end. * Standard with single lead ball screw, custom double or high lead ball screw which offers increased travel speed. Both of them require a brake or external locking device to hold position. * Power source: manual hand wheel is not recommended, electrically by brake motor drive. * Can be applied either individually use or combined into a exactly synchronized lifting system(multiple jack systems), linked by connecting shafts, bevel gearboxes, couplings, electric motors, gear reducers, limit switches and pillow blocks etc. * Can be used as alternatives to hydraulic and pneumatic systems. * High accuracy, high efficiency, high performance, high duty cycle, low backlash, long service life, and uniform lifting speed.
