HepcoMotion has introduced the ZIMM Z-Series off-the-shelf range of screw jacks that offers corrosion resistance and competitive pricing. The Z-Series features a dual lubrication system that allows the gearbox and spindle to be independently and efficiently greased. Its design includes cooling fins to improve heat dissipation. The unit comes with several mounting options to increase its application potential. A pivot bearing integrated into the gearbox housing allows it to be orientated to its optimum position through 360°.
In common with the existing ZIMM range, the Z-Series is available in a variety of sizes with thrusts up to 25kN ,and in four standard variants. As well as the TR model with trapezoidal thread, a KGT version with ballscrew is also available to reduce friction. In addition the AB Anti-Backlash version is ideal for low duty applications where adjustment to play needs to be made under alternating loads. It is therefore perfect for use in meter roller systems. The method of setting is by a simple nut that can be adjusted by the engineer to remove excess backlash in this system.
The fourth option has a SIFA safety nut that provides tension and compression load protection. In the unlikely event of the main nut failing, the safety nut will carry the full load. A sensor may be specified that stops the system when it detects thread-wear in excess of 20% of the screw pitch.
