 |
When the nut is prevented from rotating, it travels up or down the rod as the motor rotates. |

This copper alloy traveling nut (also known as a carriage nut) features a mounting flange with four holes threaded for M3 screws. It is intended for use with Tr8×8(P2) leadscrews, which are 8 mm-diameter rods with four independent trapezoidal threads spaced 2 mm apart. One full revolution of such a rod will result in a 8.0 mm linear displacement of the traveling nut.
This is the same traveling nut that is included with our NEMA 17-size stepper motors with lead screw:
- Stepper Motor with 18cm Lead Screw: Bipolar, 200 Steps/Rev, 42×38mm, 2.8V, 1.7 A/Phase
- Stepper Motor with 28cm Lead Screw: Bipolar, 200 Steps/Rev, 42×38mm, 2.8V, 1.7 A/Phase
- Stepper Motor with 38cm Lead Screw: Bipolar, 200 Steps/Rev, 42×38mm, 2.8V, 1.7 A/Phase
Please note that the nut is not spring loaded, so changes in direction will result in loss of positioning precision due to backlash.
