First chain tensioner in lightweight 3D printing

SPANN-TWIST

First chain tensioner in lightweight 3D printing

SPANN-TWIST

The tension is rising


It has never been easier to keep production running – at least when it comes to chains. They now stay perfectly tensioned, requiring significantly less maintenance and reducing wear dramatically. The reason: another innovation from MURTFELDT – the Spann-Twist chain tensioner.

With this product, we are presenting the first of its kind to be manufactured using a hybrid design, featuring a 3D-printed lightweight body and MURTFELDT Original S® material for the roller chains. It combines the best of cutting-edge technology with an iconic material: Original S® green, with outstanding properties.

All product advantages of Spann-Twist at a glance:

  • Hybrid solution combining lightweight 3D printing and MURTFELDT Original S® material
  • Open rib structure through additive manufacturing, making it significantly lighter than steel tensioners
  • MURTFELDT Original S® material offers excellent sliding properties, is wear-resistant, and operates quietly
  • Ease of assembly: multi-hole plate for flexible mounting, compact design, CAD files available
  • Curved lever movement (up to 65°) ensures even force distribution – ideal for dynamic applications
  • Adjustment range up to max. 60 mm possible, resulting in extended maintenance intervals and longer service life

The MURTFELDT Spann-Twist is suitable for these industries and applications: 

  • Special-purpose machinery 
  • Mechanical engineering
  • Conveyor systems 
  • Production facilities

As well as any application with limited installation space that requires modular, lightweight tensioning solutions.

Does the world need another chain tensioner? A good question – one we can clearly answer with “yes” after developing the first prototypes of Spann-Twist. This innovation in tensioning systems impresses with its additive manufacturing design, offering a significantly lighter weight compared to traditional cast or steel tensioners. Conventional lever tensioners, by contrast, are inflexible and prone to corrosion. And the fact that traditional tensioners require manual adjustment leaves room for costly errors. 

Spann-Twist helps save both time and money. Its modular design allows for completely hassle-free integration into existing systems. Visual markings make installation even easier by providing clear feedback. Ideal for system integration and combined use with other chain tensioners. We will soon be adding versions for rollers and sprockets. Custom adjustments to the Spann-Twist, as requested by you, are also possible after consultation.
