Slip ring technology
Slip rings / rotary joints enable data, power, signals, fluids, and gases to be transferred from a stationary to a rotating component. The slip ring is thus the centerpiece of every automated system involving continuous rotational movement: in industrial robots, machine tools, rotary tables, crane systems, and wind turbines. The available options for the manufacture of customized slip rings are as wide-ranging as our customers' requirements.
Industrial manufacturing
In the modern automation industry, slip rings are an indispensable component in all applications in which rotating machines need to be supplied reliably with current, signals, and data. Typical applications are production plants, robot systems, rotary tables, packaging machines, winding machines, wind turbines, and automated production lines – in short: in all applications that require continuous rotation and, at the same time, uninterrupted signal transmission.
Our slip rings enable production plants to work precisely and achieve maximum productivity even at high rotational speeds and under demanding operating conditions. The reliable transmission of currents, control signals, and data ensures that machine movements are exactly coordinated – without signal losses and without downtime.
Frequently asked questions (FAQ)
A slip ring is an electromechanical component that establishes an electrical connection between a stationary and a rotating part. It enables endless rotation while simultaneously transmitting power, control signals and data. Typical application areas include industrial robots, wind turbines, cranes and packaging machines.
In classic slip rings, stationary brushes slide on rotating metal tracks – in our case with Gold-on-Gold contact technology for maximum reliability. Modern high-tech variants such as fiber optic rotary joints (FORJ) work contactlessly and transmit data via fiber optic cables – wear-free and maintenance-free.
In the shop you will find industrial slip rings (our MIA bestsellers), fiber optic rotary joints (FORJ), rotary joints for media such as air, vacuum and hydraulics, as well as LubeLife maintenance oils. All standard products are transparently priced and can be requested directly.
Yes. Choose the MIA bestseller that best meets your requirements and arrange a personal consultation (approx. 15 minutes). Together we configure your slip ring to suit your application – power, signal, data or combined media transmission.
You have two options: add your desired products to the cart and request the quote directly from the cart – or enter the article number and quantity in our quote request form. In both cases you will receive a prompt reply by email from our sales team.
The service life depends on the design, rotational speed and maintenance. Our MIA slip rings achieve up to 50 million revolutions with proper use. Fiber optic rotary joints (FORJ) are wear-free and operate up to 200 million revolutions without signal loss.
