German HEISS Hydraulic Cube Cylinder HWZ 400
Product Overview
The HWZ 400 is a high-pressure square cube hydraulic cylinder developed and manufactured by HEISS, belonging to the brand’s heavy-duty compact cylinder series. Designed for ultra-high force output and limited installation space, this model features a solid cube block structure with a rated working pressure of 400 bar. Different from traditional round compact cylinders, its square integrated body delivers superior structural rigidity, stronger anti-deformation capability and higher mounting stability under extreme heavy-load conditions.
Featuring a short-stroke, high-thrust design, the HWZ 400 perfectly bridges the performance gap between 160 bar standard compact cylinders and 500 bar ultra-high-pressure cylinders. All sealing grooves strictly comply with ISO 5597/1 and DIN ISO 7425/1 international standards, ensuring universal sealing compatibility, easy maintenance and zero-leakage operation. It is widely adopted in heavy-duty clamping, precision mold locking, high-pressure pressing and mechanical positioning scenarios across industrial automation and die-casting industries.
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.

High-Rigidity Cube Block Structure
The HWZ 400 adopts an integral square cube steel structure, which outperforms conventional cylindrical cylinders in structural stability and anti-torsion capacity. Under long-term 400 bar high-pressure impact and lateral load conditions, it maintains precise positioning without deformation or displacement, greatly improving the overall rigidity and clamping accuracy of the equipment.
Balanced High-Pressure Performance & Cost Efficiency
As a 400 bar intermediate high-pressure model, the HWZ 400 provides higher thrust than 160 bar HKZ 160 series while offering better cost performance and operational stability than 500 bar ultra-high-pressure cylinders. It is the optimal choice for most medium heavy-load working conditions, balancing equipment performance and operating economy.
User-Friendly Maintenance & High Sealing Reliability
With standard international sealing groove specifications and detachable sealing assembly, the HWZ 400 enables fast disassembly, inspection and seal replacement, minimizing equipment downtime. The high-precision fitted sealing system eliminates internal and external leakage during high-frequency cyclic operation, ensuring long-term stable precision clamping.
Strong Adaptability & Diversified Customization
The series supports multiple customized variants, including high-temperature resistant sealing, water-hydraulic corrosion resistance, stroke adjustment, position sensor feedback and exhaust valve configuration. It can adapt to harsh working conditions such as high temperature, humid environment, special hydraulic media and high-frequency fatigue operation.
