East Providence, Rhode Island – Lubrication- and maintenance-free toothed belt drive actuators from igus can reduce the costs of automation tasks such as pick-and-place, inspection, and assembly applications.

drylin ZLW econ gives mechanical engineers a linear guide for light tasks that is simple and space saving. High speeds, high load, and precise positioning accuracy are not required in every application, such as format adjustment and vision system positioning. Many solutions in the market are oversized, and manufacturers pay for unnecessary features and functions or develop their own alternatives.

igus’ drylin econ is a ready-to-install entry-level series that makes simple positioning and adjustment tasks efficient and cost-effective. A belt-driven linear system, with a stroke length of 100mm, costs slightly more than $100. Using recirculating ball bearings, though more powerful, would cost nearly 3x more.

The carriage and mounting blocks are produced by injection molding, reducing the number of components and simplifying installation.

Plain bearings of the sliding carriage are made of iglide high-performance plastics, a solution 40% more cost effective than roller bearings.

The entry-level drylin ZLW econ is available with a 6mm guide shaft x 30mm base width or a 10mm guide shaft and 40mm base width. The system uses guide rails made of clear-anodized aluminum profiles, and the carriage is made of iglide thermoplastics.

A neoprene timing belt enables the carriage to maintain a linear positioning accuracy of 0.3mm. The stroke lengths can be individually determined by the user. With its lightweight construction, the actuators weigh 0.3kg and 0.7kg and can move loads up to 3kg or 10kg. Matching motor kits are also available.
