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 linear applications. Using a comprehensive range of screw diameters from 8mm through to 36mm, and combining these with two standard types of nut, (Flanged preloaded or simple flanged)  results in a high integrity lead screw and nut product that is ready to be fitted directly into the application and perform.

Lifts per Twirl ! - Screw leads from 7.5mm to 200mm as standard.

The screws can be manufactured from Steel, Stainless Steel and Aluminium whilst the associated nuts are available in wear resistant thermoplastic (Plastic Polymer Nuts: - 40 deg C to + 60 deg C) or Bronze (Bronze Nuts: - 40 deg C to + 200 deg C) for higher loads or temperature. When choosing a High helix lead screw for your application you should consider that we can offer a standard Lead Accuracy 0.21mm / 300mm or a precision Lead Accuracy of 0.10mm / 300mm.

We offer a full end journal machining service with this product, so that the product can fit suitable radial and thrust bearings.
