In automated production systems, linear axes are exposed to a variety of mechanical stresses. In addition to coarse dirt, even small parts such as screws, washers, or tools can accidentally end up in the system, for example during assembly or maintenance. This poses the risk of unexpected failures and machine downtime, thus increasing maintenance costs. In severe cases, the inability to retrieve these parts can even prevent the system from restarting. To avoid these types of problems, igus has developed the new drylin ZLX-806016-PT and SLX-806016-PT linear axes with fully integrated metal covers, designed to prevent the ingress of foreign bodies into the axis, ensuring proper system operation and operator safety.
The new drylin ZLX and SLX Protect linear axes are a fully enclosed, robust, and easy-to-install system. The integrated protective metal foil completely covers the guide rail and protects the drive from accidentally falling metal parts or the ingress of dirt. “This type of protection is particularly useful when metalworking such as welding, cutting, or bending,” explains Edoardo Rivolta, Product Manager for drylin linear technology at igus Italia. The cover also significantly reduces the risk of injury by preventing operators from coming into contact with the drive. With this solution, igus meets the needs of customers in the automation, mechanical engineering, transport systems, and packaging industries. The new Protect linear axes are particularly suitable for use in workshops and industrial machinery, but also for applications in public spaces where accessibility, safety, and continuous operation are required.
Maximum design freedom thanks to the drylin W profile
The linear axes are based on a drylin W profile made of naturally anodized aluminum, which allows for a robust and fully enclosed linear system. Designed to simplify and reduce installation time, the new igus linear axes can be mounted on aluminum structural profiles using standard, commercially available brackets. Furthermore, thanks to the groove geometry, the high profile offers maximum design freedom. “Self-supporting and compatible with the most common modular systems, they also lend themselves to the subsequent integration of additional components to adapt to specific production requirements,” emphasizes Rivolta. The igus modular range includes numerous accessories, including handwheels, position indicators, manual locks, motors, control systems, and pre-assembled carriages in three different lengths. As with all igus components, the service life of the new drylin ZLX-806016-PT and SLX-806016-PT can also be calculated prior to purchase using drylin’s online tools.
Lubrication-free, silent and dirt-resistant
In 2024, igus launched drylin ZLX, a series of high-performance toothed belt axes with a maximum axial load capacity of 1600 N and speeds of up to 3 m/s, used in automated production lines, pick & place systems, and 3D printers, among other applications. In 2025, the range was expanded with the drylin SLX variant with a lead screw drive. Designed for radial loads of up to 5000 N, it can lift loads of up to 100 kg, making it suitable for a wide range of applications in logistics, robotics, and packaging production cells. Both the ZLX and SLX axes use a linear guide system from the drylin W series, whose carriage is moved by slide strips or lead screw nuts made of the high-performance plastic iglidur J200. Solid lubricants incorporated into the material ensure low-friction, dry operation, making the system particularly quiet, dirt-resistant, and maintenance-free throughout its service life. These features allow the ZLX and SLX axes to be used in public applications requiring continuous operation, such as scanning systems, customs checks at airports, and self-service terminals in restaurants or supermarkets.
Complete turnkey solution from a single supplier
Drylin linear axes allow designers to improve the reliability of their applications while reducing maintenance costs. Thanks to their unique design, they integrate seamlessly into standard profiles used in mechanical engineering, also contributing to improved system aesthetics. “Upon request, we can supply linear axes ready for installation, complete with motors and control systems, including stepper and EC/BLDC motors. Alternatively, it’s always possible to integrate motors from other manufacturers into our solutions,” Rivolta concludes.
