Through bore slip rings are used in applications where e.g. medium needs to flow through the slip ring as in circular reclaimers or the inner space is needed for different parts or equipment. These slip ring types are used also e.g. in many cranes.
Through bore slip rings produced by Combinent have typically through bore size between 0.5m to 2m.
Split versions may have through bore with diameter of several meters. Combinent through bore slip rings are ready for installation units including enclosure, bearings, wiring, connectors, terminal boxes and requested optional equipment.
