The TR8x2 8mm OD Metric Leadscrew comes in lengths of 375mm and has a 2mm lead and 2mm pitch. This means that the leadscrew will provide 2mm of linear movement for each rotation done, often used to directly translate the precise rotational accuracy of a stepper motor into linear motion along a straight line. This is ideal for applications like 3D Printing, in which the extruder needs to move up and down with extreme precision to effectively extrude 3D Printer Filament.

The leadscrew has a 2mm pitch with a single start, which ultimately defines the 2mm lead – or linear motion of the nut. This, in comparison to a TR8x8 Leadscrew with an 8mm lead, has a slower speed but higher torque and accuracy due to the amount of stepper motor steps per mm of movement. Whereas an 8mm leadscrew would travel 8mm over 200 steps (0.04mm per step), a 2mm leadscrew like this will travel only 2mm per 200 steps (0.01mm per step) – ultimately offering four times the accuracy.

These units are sold in lengths of 375mm, to precisely fit the TEVO Tarantula 3D printers that we stock.

Typical Applications for the 8mm Metric Leadscrew TR8x2 – 375mm:

These 375mm long TR8x2 Leadscrews with 8mm outer diameter are an excellent choice for applications in which you need to convert rotational force into linear motion, such as in 3D Printers or CNC and milling machines. They act on the z-axis and allow for very precise micro-stepping movements, which is essential if you are 3D printing or drilling to extremely specific layers or heights, and offer even more accuracy and efficiency than belts due to the solid and rigid nature of the screws.

We also stock these Leadscrews in lengths of 200mm, 300mm and 500mm as well, for various applications and different sized 3D printers. Additionally, all of these leadscrews fit the TR8x2 Metric Leadscrew Nuts that we stock as well.
