Tr8x8 Lead Screw – 4-Start, 8 mm Diameter

The Tr8x8 lead screw is a nominal 8 mm diameter threaded screw for a lead-screw-driven linear motion system. It has a 2 mm thread pitch and a 8 mm lead, with 4 thread starts. A correctly matched nut therefore advances nominally 8 mm for each full screw revolution. This size is also commonly described as a T8x8 lead screw.

Technical specifications

Choose the correct lead and length

Select the cut length from the options on this product page. Each selection is for one screw of the chosen length, not a set of all lengths. The 8 mm lead determines the nominal linear distance travelled per revolution, so motor steps and motion settings must match this value.

Nut compatibility and assembly

Use a lead screw nut with the same 8 mm nominal diameter, 2 mm pitch, and 8 mm lead. A nut for a different lead or number of starts may not engage properly even if its nominal diameter is the same. Check cut length, coupling, bearing supports and any required end machining against your machine design. End machining, material grade and any included accessories are not specified by the source information.

Package contents

One lead screw in the selected length. Nut, motor coupling and bearing supports are not stated as included.
