Thomson Linear Motion Optmized
Compact Linear Systems
Take the guesswork out of specifying multiple components for your linear motion designs. Thomson compact linear systems address the need for thrust and bearing support in a single, small-scale unit for space-conscious applications. Whether you opt for one of our three standard architectures (see below) or work with our engineers on a “from scratch” solution, your application requirements will determine the selection and sizing of your system components.
Vertical Configuration (CLSV)
This architecture allows for a smaller footprint by vertically stacking the screw and profile rail bearing.
Horizontal Configuration (CLSH)
This architecture allows for a shorter system height by horizontally arranging the lead screw and profile rail bearing.
Round Rail Configuration (CLSR)
This architecture uses a dual round rail guidance system, resulting in a cost-effective solution capable of withstanding high moment loading.

- Contact Thomson for optional lead screw coatings.
- Depends on lead, nut material and lubrication.
- Depends on nut, load and orientation.
- For best positional repeatability, load should be kept well bellow design system.
- Nut fit can be adjusted depending on backlash requirements.
Compact Linear System Highlights:
- Choose from three standard architectures or build a “from scratch” system.
- Mounting blocks can be machined to virtually any shape or size.
- Virtual design consultations are like having a linear motion expert by your side as you build your solution.
- Systems can be produced and delivered quickly due to back-end modularity processes being automated.
- A 3D model of your system is made available to you in real time or typically within one business day.
Compact Linear Applications:
- Medical devices
- Security/Military
- Packaging
- Semiconductors
- 3D Printers
