High Performance, Long-Life Hollow Shaft Slip Rings
Also known as hollow shaft slip rings, our through bore slip rings use a modular design that allows for unprecedented flexibility with respect to package size and circuit count. We can provide numerous combinations of high current power circuits and low current signal circuits to meet your application requirements.
Standard units can be supplied in any of ten standard sizes, with bore diameters from 3mm to 100mm. Large diameter through bore slip rings are available as custom solutions.
TH Series hollow shaft slip rings use Orbex’s advanced channeled brush technology to greatly increase service life. This innovative design provides multiple contact points and low contact force, dramatically reducing wear in demanding applications.
