This units can be used in any electromechanical system that requires unrestrained,continuous rotation while transferring 

power or data from a stationary to a rotating 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 KYH80 series provide an economical, readily available solution when a compact through-bore configuration is required. 

This unit provides a 80 mm through-bore for routing hydraulic or pneumatic lines and a compact 180 mm outside diameter for 

minimal space applications. This series are available in 6, 12, 18, 24, 30, 36, 42 and 48 ring in standard. Similar in design 

to our very popular KYH80 series, this design features long life, fiber brush contact technology for ultimate performance in 

many challenging applications. Fiber brushes do not require lubrication and produce virtually no wear debris, for maintenance 

free, life time operation.
