AHP MERKLE HMZ Series Hydraulic Cylinders
General Overview
Model Code Definition
- HMZ 250: Series, 250 bar, magnetic‑sensor‑ready
- 40/25: Bore / Rod diameter (mm)
- 100: Working stroke (customizable)
- 10: Integrated magnetic sensor groove
- 201: Double‑acting, no cushioning
- V: NBR standard seal; E: FKM high‑temperature seal
A: Depends on the style of tie-rod. We would like to cast and forge once the quantity above 100 pcs.
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.
A: Sure, we are the manufacutuer and trading of hydraulic cylinder.
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.
A: Sure. Show us the drawing, we will quote for you soonest.
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.

Core Advantages
- 250 bar high‑pressure rating: Suitable for heavy‑duty industrial and mould applications
- Built‑in sensor groove: Saves installation space, improves sensor reliability and reduces assembly time
- Compact round‑body design: Short overall length for space‑restricted tooling and automation
- Low‑friction, stable operation: Optimised guiding and sealing system for creep‑free low‑speed performance
- High durability: Hardened chrome‑plated rod and thick‑walled tube ensure long service life
- Modular structure: Seals and sensors can be replaced on‑site simply
Typical Applications
- Die‑casting & injection moulds: Core pulling, ejection, clamping with position feedback
- Heavy‑duty machine tools: Workpiece clamping, slide drives and pressing units
- Industrial automation: Precision positioning, closed‑loop control, safety locking systems
- Automotive manufacturing: Welding fixtures, assembly stations, high‑force pressing operations
- Hydraulic presses: Stamping, forming and assembly processes requiring stroke monitoring
