| Conversion Line Starlinger ad*starKON 60|
Rotary Stroke Bearings. The complete solution.
The ad*starKON 60 from Starlinger is a state of the art conversion line to produce sacks from a fabric hose in a continuous production process. To form the bottom of the sack there are pressure pads driven by pneumatic cylinders and toggle levers. Each of the pressure pads is guided by two Mahr rotary stroke bearings in a parallel alignment.
Andreas Baci, design engineer at Starlinger, explains: ‘Mahr provides the rotary stroke bearing as a complete solution, a set exactly adjusted to our machine. With rotary stoke bearings from Mahr we improved our results significantly compared to the formerly used roller cages.’

More design freedom
Mahr is well known for their measuring tools and metrology systems. With the same precision they produce the guide bushes of the MarMotion high-precision rotary stroke bearings. In the catalog program, depending on their needs the users can find guide bushes with different kinds of sealing, e.g. to protect the bearings from coolants in a machine tool. A reliable sealing is very important for the use in the Starlinger conversion line, because the machines are running worldwide under various climatic conditions and in dusty environments.
Optimized preloading for highest guiding precision
Mahr recommends to order the rotary stroke bearing as a complete set consisting of guide bush, ball cage and guide shaft. The rotary stroke bearing is paired at the factory with a preloading optimized for a certain application. This results in a combination of high loading capacity and perfect guiding precision together with a minimized friction. The rotary stroke bearing requires low maintenance and provides a long service life. There is no need for difficult adjustments during installation. High-precision rotary stroke bearings perfectly fit in with machine tools, positioning and handling systems or grippers, measuring probes or optical devices.
In the Starlinger conversion line the rotary stroke bearings are running in 3-shifts with highest reliability and thus help to avoid expensive machine down-times in the production. Plastic sacks made of fabric provide high endurance and resistance to wear. They can be used for a wide range of applications with excellent cost efficiency. These features they have in common with high-precision rotary stroke bearings from Mahr.
