ALMA's main business is the design and production of tailor-made components and systems for complex drive requirements that also include ultra-high vacuum engineering. The product range covers high-precision vacuum components like rotary feedthroughs and direct drives e.g. for thin-film technology up to semiconductor, LED/OLED- and solar module production.
products:   ALMA vacuum rotary feedthroughs

Intelligent bearing design:   The sophisticated bearing design in all ALMA rotary feedthroughs offers numerous safety features and extreme precision, ensuring optimum true running properties and high load-bearing capacities.

Compact design with top load-bearing capacities:   ALMA focuses on creating the smallest possible design envelope for the maximum load-bearing capacity.

High-quality special magnetic fluid for maintenance-free applications:   ALMA's special magnetic fluid offers significant technical advantages: Due to its significantly lower outgassing, this fluid excels above all in applications involving thermal loading.

Reliable cooling systems for every application:   ALMA offers a comprehensive range of cooling systems for rotary feedthroughs. The product range includes simple cooling sleeves, housing and shaft cooling systems as well as combined solutions.
