Slip rings can be used in any electromechanical system that requires unrestrained, continuous rotation while transferring power or data from a stationary to a rotation structure. It's also called a rotary electrical interface, commutator, collector, swivel or an electrical rotary joint. It can improve electromechanical capability, simplify system design, eliminate possible damage while rotation. It's the key apparatus of various precision rotary worktable, electric test instrument, manufacture and process control instrument.
The unobstructed bore through the center provides routing space for hydraulics, pneumatics or for a concentric shaft mount. Our through bore slip rings feature our fiber brush technology which offers several advantages over conventional slip ring technology including multiple points of contact force per fiber and low contact wear rates. In addition, fiber brushes do not require lubrication and produce virtually no wear debris. The through bore from 12.7mm, 25.4mm, 38.1mm, 50.00mm to 500mm are optional. The current from 2A to 300A are optional, which can satisfied your different schemes.
