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.
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.
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
