Twin lead screws from Helix Linear Technologies are designed to produce dual opposing motion using a single drive system. This one-piece screw delivers simultaneous right and left movement from a centerline. Ideal for high-performance applications with low duty cycles or manual drive operation, the advantages of using twin lead screws include easy installation and elimination of alignment problems.

Twin lead screws from Helix Linear technologies offer dual opposing motion using a single drive system. That's right - simultaneous right and left movement from a centerline, but on a single drive system or motor. This one-piece screw is designed for high-performance applications, offering several advantages, including easy, convenient installation and elimination of alignment problems associated with segmented versions.

Twin-lead Acme screws are typically made from alloy steel and black oxidized for further protection. Depending on the intended application, they can be easily assembled with the various nuts, flanges, and EZZE-MOUNT bearing supports to offer enhanced support in a cost-effective manner.

Twin lead screws are ideal for high-performance applications with low duty cycles or manual drive operation. Some popular applications include:

  • Molding machines
  • Packaging equipment
  • Food processing machinery
  • Robotics
  • Material handling applications
  • Tire manufacturing

Twin lead screws from Helix Linear can be completely tailored to fit the requirements of your application. Customizations include material, thread form, end-machining, coatings, nut type, nut material, and mounting options. The most popular type of twin lead Acme screws are thread-rolled screws. Thread-rolled twin lead screws offer a standard lead accuracy of 0.0003 inches but can be modified for additional accuracy. Rolled twin lead screws more economical than ground screws making them a cost-effective option.
