Anti-Backlash Screw Jacks Screw jacks are used for positioning loads in numerous applications, however when the load direction alternates between tension and compression within the operating cycle and a high position accuracy must be maintained then a specific type of screw jack is required. The Anti Backlash Machine Screw Jacks is recommended for such applications, as it is able to reduce the axial backlash between the lead screw and the trapezoidal screw thread in the gear to a practical minimum. Axial backlash exists in standard screw jacks as the "gap" or "play" between the flanks of the lead screw thread and the internal thread on the worm gear nut. This gap or play is due not only to normal manufacturing tolerances, but to the fact that there must be some clearances to prevent binding and galling when the screw jack is operating under load. In most applications either the load direction is constant so axial backlash does not occur or the position error

Hand Operated Upright Rotating Machine Screw Actuator 5Ton And 2963MM Long Acme Screw And Acme Nut For Conveying Rails In Rail Train In South Africa. 1. Upright Rotating Machine Screw Actuator 5ton fitted on base with special dimensions bronze travelling nut. 2. 2963mm long shaft with 2763 mm ACME thread Part of end not threaded at both ends will require diameter 19. Thrust bearings at both ends of horizontal screw. Both items require simular ends (16x16mm square x 30 mm long) 3. Machine Screw Actuator Load Capacity in general = 5000kg maximum 4. Traveling speed is by hand, however maximum travel per turn possible will be important. 5. The equipment is used on a rail train that conveys 48 of 60kg/m rails of 240 meters long. Offloading takes place two rails at a time. 48 Rails can be offloaded in one day. Offloading of 48 rails can happen up to about four times per week and continue almost whole year long. 6. Working conditions it typically South African w
