AHP MERKLE BZ 02 Stamping Cylinder Introduction
OVERVIEW
The BZ 02 (commonly referred to as AHP02 in the industry) is a high‑pressure, heavy‑duty block cylinder designed by AHP Merkle GmbH (Germany) for stamping, die, and high‑force mold applications. The 02 denotes front flange mounting, the most popular version for stamping and tooling.
Brand & Overview
- Brand: AHP Merkle GmbH (founded 1973, Germany)
- Model: BZ series (square block cylinder) + Mounting 02 (front flange)
- Type: Double‑acting, compact, high‑pressure hydraulic cylinder
- Primary Use: Stamping, punching, bending, clamping, core pulling, and slide driving in press dies, automotive tooling, and high‑cycle molds
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 Ratings
- BZ500: Max 500 bar (7,250 psi) – standard for stamping
- BZ320: Max 320 bar (4,640 psi)
- BZ250: Max 250 bar (3,625 psi)
Sizes (mm)
- Piston diameter (bore): Ø16, 20, 25, 32, 40, 50, 63, 80, 100, 125, 160, 200
- Rod diameter: 12, 16, 20, 25, 32, 40, 50 (matched to bore)
- Standard strokes: 5, 10, 16, 20, 25, 32, 40, 50, 63, 80, 100, 125, 160, 200
- Stamping typical stroke: 10–100 mm (short stroke, high frequency)
- Max custom stroke: 500 mm
Materials & Construction
- Cylinder body: High‑strength alloy steel, monolithic square block – excellent rigidity, resists side loads and bending
- Piston rod: Hardened → precision ground → hard chrome‑plated → mirror polished – high wear resistance, impact fatigue strength, low friction
- Seals:
- Standard: NBR (‑20 °C to +80 °C)
- High‑cycle/high‑temp stamping: Viton (‑20 °C to +180 °C) – anti‑impact, anti‑extrusion seal package
- Guidance: Reinforced guide rings + wear bands – absorbs stamping side loads and misalignment
- Heavy‑duty guidance: Longer guide length, upgraded wear bands for high side loads
- High‑flow ports: Larger port size for fast response, high‑speed cycling
- Impact‑resistant seals: Special seal geometry for pressure spikes & shock loads
- End‑of‑stroke cushioning (optional): Reduces noise, prevents shock damage, extends service life
- Position sensing (optional): Magnetic/inductive switches for stroke end confirmation & automation
