Linear axes at a glance: the right drive for your system

drylin drive technology consists of a wide range of products ranging from lightweight linear axes made of polymer to solid stainless steel solutions; they work without the use of external lubricants. The movement of the linear axes is implemented either via lead screws, toothed belts or racks. igus offers the customer suitable solutions for the most individual applications. In all systems, the length of the stroke is freely selectable and the drive of the linear units can be implemented using optionally available equipment in the form of hand wheels or various motors. Positioning tables driven by lead screws are the preferred choice for applications with high axial shear forces, which therefore require the highest precision.

Across models, the linear modules can be equipped with trapezoidal or high helix lead screws.  Linear axes with toothed belt drives are designed for long travels and highest speeds in applications with high repeatability and short cycle times.  
 
The  linear units for high speed and long travels with direct power transmission via racks offer the additional benefit of allowing multiple carriages to move independently and clearance-free of each other, on one system.
