    High Helix Lead Screws

    The revolutionary high helix multi-start lead screws can offer leads of up to 6 x the diameter of the screw. This multi-start  lead screw product provides high linear nut speeds from low rotational screw speeds.  Aimed at replacing timing belt mechanisms or executing fast and reliable linear motion the efficient conversation of linear to rotary movement makes this unique product usable in many applications. Formed by the cold rolled forming process, the screws are proving to be a superb economical solution for high speed linear applications.

    Lead Screws

    Matching leads in right handed and left handed lead screw formats.

    Lead screws supplied in both a right handed and left handed thread format can readily be supplied by Abssac limited. A redesigned food packaging machine was originally using the opposing screws to operate a high speed gripper in a machine that hot plastic foil sealed, ready to cook meals for a leading supermarket. Since the machine operated within a food grade environment meant there could be no lubrication with the system, which contributed to the premature failure of the nuts after only 50,000 cycles.  It was also a concern that the existing lead accuracy matching between leadscrews could also be a factor in the excessive wear of the nuts.

    By utilizing a PTFE impregnated plastic as the antibacklash nut base material and ensuring matched pitch accuracy of the screws in both the right handed and the left handed screws enabled initial tests cycles up to 56,000 cycles to be completed without any sign of wear to the nuts. Phil Jones of Abssac says” By being able to match the screws pitch accuracy reduces the stresses within the system considerably ensuring a more reliable linear movement”
