500 Series Hollow Shaft Slip Rings


Orbex’s 500 Series of through bore slip rings (or hollow shaft slip rings) are ideally suited for electrical and electromechanical applications where signals and power need to be transferred in a compact space and a through-hole is required to pass a shaft or other feed through.

Innovative Slip Ring Technology from Orbex

Orbex 500 Series hollow shaft slip rings feature a modular design that allows for unparalleled flexibility with respect to package size, circuit count, and mix of power and signal circuits. We offer a variety of high current power circuit/low current signal circuit combinations to meet your application and performance requirements.

Standard units are available in eleven sizes, with bore diameters from 2 mm to 100 mm. Larger diameter through bore slip rings are available as custom solutions—contact us for custom slip ring units.
