The Orbex Group is a leading manufacturer of slip rings and precision electric motors.

Hollow Shaft/Through Bore Slip Rings

Orbex 500 Series through bore slip rings are ideal for applications where signals and power need to be transferred, and a through hole is required to pass either a shaft or other feed through. Designed for compact spaces, they are especially well-suited for use as wind generator slip rings.

Our hollow shaft slip rings use a modular design that allows for unprecedented flexibility with respect to package size, circuit count, and the mix of power and signal circuits. Standard units can be supplied with bore diameters from 2mm to 100mm. Larger diameter through bore slip rings are available as custom solutions.

500 Series hollow shaft slip rings use Orbex’s advanced channeled brush technology to greatly increase service life.
