dryspin threaded spindle technology from igus: an innovative solution for linear motion

Threaded spindles are essential components for many machines and devices that require linear motion, such as door operators, elevators, robots, 3D printers and more. Threaded spindles convert rotational motion into translational motion through a thread that engages a nut. The quality, efficiency and life of a threaded spindle depend on material selection, thread shape, pitch, friction, lubrication and, of course, environmental factors and the application itself.

igus of Soesterberg (from Q2-2024 the branch will move to Amersfoort), a leading company in the field of polymer energy supply systems, cables, low-cost automation solutions and linear technology, has developed a unique solution for threaded spindle technology: dryspin. dryspin is a patented technology based on the principle of lubricant-free and maintenance-free linear engineering. dryspin combines spindle nuts made of tribo-polymers with options in hard-anodized aluminum, steel or stainless steel wire spindles with an asymmetrical spindle geometry. This combination offers numerous user benefits, including:

• Lower friction and higher efficiency: due to the flat thread angle, the inserted force is efficiently converted into a translational movement. The spindle nuts have a low coefficient of friction and high wear resistance, reducing energy requirements and heat generation.
• Longer life and lower costs: dryspin threaded spindles have up to 30% longer life than conventional threaded spindles, thanks to the optimal alignment between the spindle nut and threaded spindle. In addition, the spindle nuts and threaded spindles are up to 60% lighter than all-metal alternatives, reducing weight and inertia. Polymer spindle nuts are up to 50% cheaper than metal spindle nuts, reducing procurement costs.
• Lubrication-free and maintenance-free: dryspin spindle nuts are available in seven different materials that feature integrated solid lubricants, so they never need lubrication, making them excellent for dirty, dusty or humid environments. They are also resistant to corrosion, chemicals and temperatures up to 200°C. dryspin threaded spindles do not require regular maintenance or cleaning in similar solutions that require them. Thus reducing downtime and operating costs.
• Individual (online)( configuration and easy assembly: dryspin threaded spindles are available in different variants, such as steep, trapezoidal and metric threads, with right, left or reverse threads, and with different outside diameters and pitch. The threaded spindles have up to 30% longer life than traditional spindle systems. Users can also create their own custom solution online. configure, with individual final machining, CAD data, lifetime calculation, price calculation and ordering capability. dryspin threaded spindles are easily assembled using accessories such as flanges, clamps, couplings and handwheels.

dryspin threaded spindle technology from igus is an innovative linear motion solution that offers the user many advantages in terms of performance, durability, cost and flexibility. dryspin threaded spindles are suitable for a wide range of applications, such as medical technology, laboratory automation, mechanical engineering, automation, packaging machinery, food processing, food industry, woodworking, agriculture and many more.
