Mobile stone wire saw

• What was needed: Linear rails with high rigidity and carriages for high loads, as well as plain bearings that are particularly low-maintenance and lubrication-free
• Requirements: Corrosion resistance, dirt-resistant, low-maintenance/maintenance-free, support of heavy loads
• Products used: drylin® linear technology, iglidur® plain bearings, e-chain®
• Success for the customer: Longer service life of the masonry saw thanks to low-maintenance parts from igus®

Quarries are often difficult to access and require specialised equipment. A mobile stone wire saw is a proven solution for cutting natural stone blocks in quarries, as it offers a flexible and effective method of cutting heavy natural stone.
However, the machine must be robust and powerful to withstand the hard and resistant rocks. Particularly high demands are placed on the machine's bearings. Due to the lack of water in the quarry, permanent cleaning of the bearing points cannot be guaranteed. Contamination of the rock by lubricants, for example, must be prevented. igus® ensures that these requirements are met with its parts from the drylin® and iglidur® product range.

For this area of application, igus® offers the drylin® W series, which was specially developed for use in harsh environments. These systems use self-lubricating tribo-optimised materials as sliding elements, which gives them high corrosion resistance and a good service life. This specification makes them ideal for use in the natural stone industry, where weather fluctuations and harsh working conditions are often a challenge. drylin® W-linear guides are configurable online in different sizes. They offer high rigidity and strength to cope with load during the cutting process, ensuring fast and quiet running as well as a precise control system of the cutting arm. 
The Q2 bushes are a central component of the saw. This is partly due to the excellent damping properties compared to brass bushes. However, the most important specification is that they are lubricant-free. This prevents the rock from being contaminated by dripping lubricant.
Based on his positive experience with our products, the customer also opted for one of our energy supplies, the E4Q energy chain with an inner height of 58 millimetres.
Our components make the saw robust reliable in its daily work in the quarry. Schwing and igus® are thus creating a sustainable and cost-saving way of cutting stones directly on site, thereby significantly reducing material consumption, time and CO2 emissions in the production process. The conclusion of the collaboration is therefore very clear for Daniel Kriegl: "The support is great and you really have to say that the igus® products are a perfect fit for our application"
