• Through Hole Slip Rings – DHK large inner hole Series

Available for custom, standard ID 3-500 mm, OD 10-800 mm  

DHK310-78 series extra-large-diameter hollow shaft slip rings, with an inner bore of 310mm, are suitable for rotating electromechanical systems with a bore diameter of less than 310mm. They feature a standard power ring rating of 20A per ring, with a maximum of 48 rings, and a signal ring rating of 5A per ring, with a maximum of 96 rings. They utilize stainless steel construction and are designed for transmitting power or signals in 360-degree rotating systems. They can be used in automated industrial control systems, automated electrical transmission systems, and intelligent loading robots.

• Typical Applications:

  • Automatic machinery
  • Cable reel

  • Display/Display Equipment
  • Packaging Machinery
  • Industrial turntable
  • Medical/pharmaceutical equipment
  • Marking machine
  • Filling Machinery
  • CNC machine tool

• Product Naming Description

 DHK310-78

(1)Product type: DH—electric slip ring
(2)Installation method: K—through hole
(3)Through hole product bore diameter10 mm
(4)Total circuits:16 circuits
(5)The rated current or it will not be marked if it passes through a different rated current for the circuits.

(6) Identify number: –XXX; In order to distinguish different specifications of the same product model, the identification number is added after the name. For example: DHK080-24 has two sets of products with the same name, the cable length, connector, installation method, etc. are different, you can add the identification number: DHK080-24-002; if there are more of this model in the future, and so on -003 , -004, etc.
