Available Modifications & Customized Solutions

We can quickly modify our standard slip rings to fit your needs, Also, Our Custom Solutions Tailored to Meet Your Project's Exact Requirements!


A slip ring is an electromechanical device that facilitates the transmission of electrical power and signals from a static to a moving part.
They are used in almost all electromechanical machines which call for unrestricted, discontinuous or continuous spinning while conducting power and signals.
Slip rings can enhance the mechanical performance of a machine, streamline system functionality, and eradicate damage-prone wires hanging from rotating joints.
They function by making continuous electrical connections from stationary systems to rotating systems. Slip rings can also be called swivels, rotary joints, collectors, or commutators.
A slip ring assembly comprises of brush blocks, which are accurately harmonized and usually available as a set of a ring and a brush.
The MOFLON slip rings are designed to endure harsh environmental conditions like acidic and salty media and extreme vibrations. Besides, our products guarantee a reliable operation of the whole equipment system.
