Precision T Lead Screw Stepper Motor , NEMA 17 42mm Stepper Motor

NEMA 17 42mm Stepper Motor T-lead Screw Linear Motion Slide Stage Module

Product Introduction

This 42mm stepper motor electric linear slide stage with T-lead screw is an integrated linear transmission unit combining a 42mm stepper motor, precision T-lead screw, linear guide rail, and moving slider. Designed for stable, accurate linear reciprocating motion in automation scenarios, it is easy to install and can directly connect to various control and execution systems, significantly reducing mechanical design and assembly costs for projects.

Core Product Features

High-compatibility 42mm Stepper Motor with Customizable Performance

• Standard 42-series stepper motor available in multiple specifications: body lengths of 40/48/60/63/80mm, corresponding torques from 45Ncm to 1.4Nm, and rated currents from 1.3A to 2.8A, meeting different load and speed requirements.
• The metal flange and rigid coupling ensure coaxial alignment between the motor and the lead screw, eliminating backlash, delivering high power transmission efficiency, and reducing vibration and noise during operation.

Precision T-lead Screw Drive with Flexible Stroke and Lead Options

• The lead screw offers three lead options: 2mm/4mm/8mm, balancing low-speed high-thrust and high-speed movement needs. The single-line T-lead screw ensures smooth transmission and excellent self-locking performance, preventing slider displacement after power-off.
• Available stroke lengths: 50/100/150/200/250/300mm. Customizable strokes are available to suit different installation sizes and motion range requirements.

Linear Guide Rail + Metal Slider for Stable and Durable Operation

• The high-precision linear guide rail paired with reinforced metal bearing plates delivers strong load capacity, ensuring smooth, jitter-free slider movement, high repeat positioning accuracy, and resistance to deformation during long-term use.
• The moving slider features a wear-resistant design with a dedicated lead screw nut, effectively reducing transmission wear, extending the module's service life, and supporting long-term continuous operation.

Integrated Modular Design for Easy Installation and Maintenance

• The module is pre-assembled and calibrated at the factory, ready for installation right out of the box without complex machining or alignment.
• Standard mounting holes allow direct connection to mainstream control equipment such as 42mm stepper motor drivers and PLC control boards, enabling rapid setup of automation systems and significantly shortening project development cycles.

Typical Application Scenarios
