igus® Introduces Compact, PTFE-Free Linear Guide for Precise Positioning

Engineered from lubrication-free, high-performance polymers and aluminum, the guide offers a lightweight, hygienic and low-maintenance alternative to complex mechanical and electronic adjustment systems.

igus®, a global leader in motion plastics, introduces its drylin® WWP linear guide featuring a PTFE-free locking carriage. Engineered from lubrication-free, high-performance polymers and aluminum, the guide offers a lightweight, hygienic and low-maintenance alternative to complex mechanical and electronic adjustment systems.


"Many manufacturers require a minimalist linear guide with a snap function that eliminates the need for levers or intricate mechanical and electrical components," says Michael Hornung, Product Manager for drylin® Linear and Drive Technology at igus®. "To meet this demand, the drylin WWP linear guide has been developed to offer an uncomplicated and cost-effective solution."

Intuitive, Reliable Positioning
The drylin® WWP linear guide features two key components: a polymer carriage that attaches to the moving object and an aluminum linear rail that facilitates smooth adjustments.

Integrated polymer rings at set intervals along the rail interact with a preloaded steel ball on the carriage underside, creating an audible click when securing objects in position. The system's maximum static load capacity is 100 and 50 Newtons (N) in the vertical and horizontal directions, respectively. For repositioning, an applied force disengages the ball, enabling movement until it locks into the next preset position.

Lightweight, Durable and PFAS-Free
The linear rails are available in lengths up to 3,000 millimeters and can be customized with hard anodized, silver anodized or black anodized finishes. To meet specific mounting needs, igus® offers rail profiles without pre-drilled holes. Polymer carriages are available in two sizes.

Compared to traditional recirculating ball-bearing systems, the drylin® WWP guide is also more compact and lightweight, offering a weight reduction up to 65% versus aluminum carriages. This design makes the guide ideal for applications where space and weight are at a premium, such as vehicle and aircraft interiors and furniture.

The drylin® WWP carriage is manufactured from a high-performance polymer embedded with solid lubricants, ensuring continuous smooth operation without needing external lubrication. The material is free from approximately 100 PFAS chemicals, aligning with future regulatory requirements and meeting low-fogging standards for the automotive industry.
