HEISS High-performance Multi-channel Hydraulic Rotary Union Multiport Swivel
Product Overview
The HEISS Multiport Swivel is a high-performance multi-channel hydraulic rotary union specially developed for continuous fluid transmission under rotating and swinging working conditions. As a core auxiliary component matching HEISS hydraulic cylinder series, this swivel joint enables stable, leak-free medium delivery between stationary pipelines and continuously rotating equipment. It effectively solves common industrial pain points such as pipeline torsion, tensile damage, oil leakage and pressure loss caused by mechanical rotation.
Adopting standard DIN ISO 12240-4 E-series design specifications, the HEISS Multiport Swivel features a compact integrated structure, high-precision bearing system and durable composite sealing configuration. It supports simultaneous transmission of multiple independent hydraulic, pneumatic or cooling medium channels without mutual interference. With optional maintenance-free sealed bearings and corrosion-resistant structural versions, it delivers long-cycle stable operation and strong environmental adaptability, perfectly matching automated fixtures, rotary tables, mold equipment and multi-axis rotating hydraulic systems.
Q: What’s the MOQ of customized tie-rod cylinder?
A: Depends on the style of tie-rod. We would like to cast and forge once the quantity above 100 pcs.
Q:What’s the lead time of customized tie-rod cylinder?
A: Well, it depends on the quantity and style of hydrualic cylinders, at least 60 days if we make casting and forging, at least 35 days by maching.
Q: Are you the manufacturer of hydrualic cylinder?
A: Sure, we are the manufacutuer and trading of hydraulic cylinder.
Q: What is the difference between double acting and single acting cylinders?own controlled by the pump or the valve or is it only one speed?
A: Double-Acting-have a port at each end, supplied with hydraulic fluid for both the retraction and extension. Single-Acting-hydraulic fluid enters through
a port at one end of the cylinder, which extends the rod by means of area difference. An external force or gravity returns the piston rod.
Q: I have a drawing, could you customized cylinder as my drawing?
A: Sure. Show us the drawing, we will quote for you soonest.
Q: Could you make the cylinder which is not on the above data sheet?
A: Yes, we make and supply a wide rang of hydrualic cylinders as a proffetional manufacture, there are only some kinds of them show on the website. Freely contact us to get more information.
