Overview

This document details technical specifications, mounting options, and ordering information for standardized hydraulic cylinders compliant with DIN and ISO standards (DIN/ISO 6020/1 and DIN 24333 / ISO 6022). It covers two main series: DHZ 160 (max pressure 160 bar) and DHZ 250 (max pressure 250 bar).

General Characteristics

• Hydraulic cylinders conform to DIN/ISO norms.
• Maximum operating pressures: 160 bar (DHZ 160) and 250 bar (DHZ 250).
• Piston diameters range from 25 mm to 200 mm.
• Piston rods are hardened, ground, and hard chrome plated for durability.
• Multiple mounting options and a wide range of accessories available.
• Standard double-acting operation with options for end-of-stroke and controllable cushioning.
• Standard venting at both ends.
• Optional Viton® seals for high-temperature applications (up to 180 °C) and compatibility with HFD fluids.

Mounting Options

Various mounting modes are identified by numeric codes (e.g., 00, 001, 02, 05, 07, 08, 10, 11, 12, 22, 55), including:

• Rectangular flange (front and back)
• Base mount (foot mounting)
• Pivot eye and pivot joints (front, middle, back)
• Round flange (front and back)
• Attachment threads (front)

Each mode has specific dimensional parameters such as piston diameter, rod diameter, thread sizes, and stroke lengths. Non-standard piston diameters and mounting options are available on request.

Operation Modes

• Standard double-acting cylinders.
• Double-acting with end-of-stroke cushioning (front, back, or both sides).
• Controllable cushioning options.

Connection and Adjustment Features

• Hydraulic connections positioned per ISO standards with angular configurations (90°, 60°, 45°).
• Standard adjustment screws for cushioning and vent screws.
• Check valves integrated in some configurations.

Technical Data and Dimensions

Detailed tables provide dimensions for each cylinder size and mounting mode, including:

• Piston diameter (d1)
• Rod diameter (d7)
• Mounting thread sizes (d5)
• Customizable stroke lengths
• Various length parameters (L3, L4, L6, L8, L15, etc.)
• Nominal static pressures: 160 bar (DHZ 160), 250 bar (DHZ 250)

Dimensions are in millimeters and subject to change without notice. Calculations are based on AHP data.

Ordering Information

Orders use a structured code indicating piston diameter, stroke, mounting mode, operation mode, and rod diameter. Examples are provided for clarity.

Additional Notes

• All cylinders have venting at both ends as standard.
• Special designs and options available upon request.
• Technical changes reserved without prior notice.

Summary of Critical Parameters

• Max operating pressure: 160 bar (DHZ 160), 250 bar (DHZ 250).
• Piston diameter range: 25 mm to 200 mm.
• Multiple mounting modes with detailed dimensional data.
• Standard double-acting operation with cushioning options.
• Viton® seal option for high temperature and HFD fluids.
• Standard venting at both ends.
• Custom stroke lengths and special configurations available.

Technical Specifications and Dimensions

The document provides detailed specs focusing on piston diameters, rod diameters, mounting modes, and operation modes. Mounting modes include 00, 04, 07, 08, 11, 22, and 55, each with specific dimensional parameters.

Key Parameters

• Piston Diameter (Ød7): 50 mm to 200 mm and beyond, including some non-standard sizes.
• Rod Diameter (Ød1): Corresponding to piston sizes, ranging from 32 mm to 125 mm.
• Mounting Modes: Various codes define fixing and operational configurations.
• Nominal Pressure: Static nominal pressure consistently 250 bar (3600 PSI) across configurations.
• Thread Sizes: M27x2 to M100x3, matching piston sizes.
• Dimensions: Detailed millimeter dimensions (d2, d3, d4, B8, B7, B, A, d6, etc.) for precise engineering.

Mounting and Operation Modes

Mounting modes are categorized by codes with corresponding operation modes indicating cylinder function. Each includes dimensional data and designations for stroke and other measurements.

Examples of Mounting Modes

• Mode 00: Basic mounting with standard dimensions.
• Mode 04: Includes stroke and hub variations.
• Mode 07 and 08: Specialized mounting modes with detailed dimensions.
• Mode 11, 22, 55: Advanced mounting options with specific design parameters.

Seal Kits and Spare Parts

Comprehensive seal kits are available for different piston diameters and mounting modes, including:

• Standard Seal Kits
• Viton® Seal Kits for enhanced chemical resistance.

Seal kits cover piston diameters from 25 mm to 200 mm and various mounting modes. Part numbers facilitate ordering.

Availability and Notes

• Seal kits are stocked and available for immediate delivery.
• Some piston diameters and mounting modes are non-standard and may require special ordering.
• Dimensions in millimeters; technical changes subject to notice.
• Calculations based on AHP data ensure engineering accuracy.

General Recommendations and Notes

• Static nominal pressure should not exceed 250 bar (3600 PSI) for safe operation.
• Custom specifications can be accommodated upon request.
• Technical data is subject to change; users should verify current specs before design or ordering.

This structured data supports precise engineering, ordering, and maintenance of hydraulic cylinders with various mounting and operational configurations.
