    AHP MERKLE ZSE Push Unit – Product Introduction

    The ZSE series (also called HZ‑based Push Unit) is a robust, cost‑effective guided hydraulic thrust device from AHP Merkle GmbH (Germany). Built on the proven HZ standard cylinder platform, it integrates a block‑style cylinder with 2–4 guide columns, optimized for general‑purpose pushing, deburring, cutting, and automation tasks at 250 bar.

    Brand & Product Overview

    • Manufacturer: AHP Merkle GmbH (Germany, founded 1973)
    • Series: ZSE 250 (standard), ZSEP 250 (with position switches)
    • Type: Double‑acting guided push unit (HZ cylinder + guide columns)
    • Max. Operating Pressure: 250 bar (3,625 psi)
    • Core Concept: Cost‑optimized alternative to BSE, using HZ‑series cylinder components for ruggedness and shorter lead times.
    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.

    Pressure & Force

    • Max pressure: 250 bar (all ZSE 250 models)
    • Bore sizes: Ø32, 40, 50, 63, 80 mm (HZ‑based, fewer bore options than BSE)
    • Rod diameters: 20, 25, 32, 40, 50 mm (matched to bore)
    • Standard strokes: 50, 75, 100 mm (custom strokes available)

    Guidance & Construction

    • Guide columns: 2, 3, or 4 (hardened, ground steel)
    • Cylinder body: High‑strength alloy steel, monolithic block design (HZ series)
    • Piston rod: Hardened → precision ground → hard chrome‑plated (wear/corrosion resistance)
    • Seals:
      • Standard: NBR (‑20 °C to +80 °C)
      • High‑temp: Viton (‑20 °C to +180 °C) (option code F)
    • Front plate: Optional guided front plate for direct tool mounting

    Mounting Options

    • 01: Mounting holes, with guide columns, without front plate
    • 02: Mounting holes, with guide columns and front plate
    • 11: Mounting thread, with guide columns, without front plate
    • Cost‑effective: Lower price than BSE (uses HZ standard components)
    • Robust & reliable: HZ‑based design for heavy‑duty, continuous operation
    • Good lateral load resistance: Guide columns handle moderate side forces (up to 20% of axial force)
    • Compact footprint: Integrated cylinder + guidance saves space vs. separate assemblies
    • Fast delivery: Large stock of standard models; 15+ bore/stroke combinations available

     

    • Deburring tools: Linear thrust for edge deburring in metalworking
    • Cutting units: Precision push for blanking, piercing, or trimming
    • Mold & die: Slider actuation, core pulling, clamping in injection/die‑cast molds
    • Automation: Linear actuators for assembly lines, part positioning, medium‑duty clamping
    • General machinery: Cost‑effective thrust for space‑restricted tooling
