DHK with through bore Series

Through Bore Slip Rings – DHK Series: Versatile Slip Rings for Cable and Shaft Passage

The DHK series through bore slip rings are designed with a hollow shaft, ideal for routing cables, pipes, shafts, or other axial components through the center of the rotating assembly.
These axial slip rings are widely used in industrial automation, packaging machinery, wind turbines, and high-performance rotary systems.

Thanks to their modular and fully customizable design, DHK slip rings are available in configurations from 2 to 350 rings, supporting currents from 2A to 6000A, with through bore diameters ranging from 3 mm to 300 mm. Mounting flanges, shaft collars, and custom gear interfaces are available on request.

Built with multi-contact precious metal brushes, they ensure low electrical noise, high-speed data transmission, low contact pressure, and a long service life with zero maintenance.
