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. The video shows the comparison of the distance the nut will travel for one revolution of the screw between a fine thread and fast high helix thread.
