AHP MERKLE BZS 500 Series
General Overview
The BZS 500 is a high‑pressure, heavy‑duty push unit (slide unit) with integrated guide columns, designed and manufactured by AHP Merkle GmbH (Germany). It combines a 500 bar block cylinder (BZ 500) with a precision guide system, engineered for high‑force linear motion, clamping, pressing, and core pulling in tooling, molds, and automation.
BZS is the high‑pressure counterpart of the BSE 250/ZSE 250 series, built for applications requiring extreme thrust, precise guidance, and high resistance to lateral loads.
Model Code Explanation
BZS 500.40/25/100.4.201.E
- BZS 500: Series (500 bar push unit with guide columns)
- 40: Bore diameter (mm)
- 25: Piston rod diameter (mm)
- 100: Working stroke (mm)
- 4: Number of guide columns (2, 3, or 4)
- 201: Double‑acting, no cushioning
- E: FKM high‑temperature seal (V = NBR standard 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.
- Max Working Pressure: 500 bar (7,250 psi).
- Cylinder Type: Integrated BZ 500 square block cylinder.
- Guide System: 2, 3, or 4 high‑precision guide columns (hardened, ground, hard‑chrome plated).
- Bore Sizes: Ø 25, 32, 40, 50, 63 mm (standard).
- Standard Rod Diameters: 16, 20, 25, 32, 40 mm.
- Standard Stroke: 50, 75, 100 mm (custom strokes up to 200 mm available).
- Temperature Range:
- NBR seals (V): −20 °C ~ +80 °C.
- FKM seals (E): −20 °C ~ +120 °C (optional up to 180 °C).
- Guidance: Long guide length for high lateral force absorption; guide columns with low‑friction bearings.
- Mounting: Multiple options (front flange, foot, tapped holes, rear clevis).
- Position Sensing: Compatible with magnetic field sensors (optional integrated sensor grooves).
Core Advantages
- 500 bar ultra‑high pressure: Delivers up to ~980 kN thrust (Ø50 mm bore) for heavy‑duty operations
- Integrated precision guidance: 2–4 guide columns absorb high lateral loads, preventing rod bending and ensuring linearity
- Compact & rigid: Square block design saves space; heavy‑duty steel construction minimizes deflection
- High efficiency: Optimized flow design reduces power requirements; fast movement even at high loads
- Durability: Hardened rods/columns + premium seals ensure long service life in harsh environments
- Modular & customizable: Flexible mounting, stroke, seal, and sensor options; easy on‑site maintenance
Typical Applications
- Injection mold & die‑casting: Core pulling, ejection, clamping with high force and precision.
- Heavy machinery: Workpiece clamping, slide drives, pressing units for metal forming.
- Automation: High‑force linear positioning, safety locking, assembly stations.
- Tooling: Deburring, cutting, and stamping tools requiring guided high‑force actuation.
- Hydraulic presses: Stamping, forging, and assembly processes with stroke monitoring.
