Cylinder

Product catalog summary

Overview: This document outlines the technical specifications and guidelines for the Hydraulic Standard Cylinder Series DZ25 by HOERBIGER, covering design, mounting styles, dimensions, and operational parameters.

Specifications:

Design: Features a compact design with optional cushioning. Available in four mounting styles: thread at cylinder head, spherical eye at cylinder bottom, round flange at cylinder head, and trunnion at cylinder head.
Pressure Ratings: Nominal and operating pressure is 250 bar, with a static test pressure of 375 bar.
Temperature and Medium: Operates between -30°C and +70°C, using mineral oil as per DIN 51524 and 51525, with other media available upon request.
Sealing Types: Offers standard and low-friction seals.

Mechanical Characteristics:

Piston and Rod Dimensions: Piston diameters range from 32mm to 160mm, with corresponding rod diameters.
Area Ratios: Provides detailed area ratios for piston and annulus areas.
Cushioning: Options for cushioning at the head, bottom, or both ends, with specific damping ratios.

Mounting and Dimensions:

Includes detailed dimensions for each mounting style, dependent on piston diameter, with specific measurements for thread, spherical eye, round flange, and trunnion mountings.

Operational Guidelines:

Speed and Cushioning: Maximum piston speed is 0.5 m/s. End position cushioning is recommended for speeds over 0.1 m/s.
Load Characteristics: Provides guidelines for determining piston rod diameter based on load cases, advising against unfavorable load conditions.

Load Characteristic Determination: Describes the process for determining the load characteristic (α) and the extended length (L) of a piston rod, with the unsupported length (sK) calculated as the product of α and L.

Piston Rod Load Diagram: Offers a method to determine the rod diameter from the piston rod load diagram, including different cases based on the load characteristic, with specific formulas for calculating the unsupported length (sK) for each case.

Example Calculation: Provides an example for a cylinder with a load characteristic of 1 (α=2) and an extended length of 760 mm, resulting in an unsupported length of 1520 mm. For a pressure force of 64 kN, the piston rod diameter is determined to be 56 mm.

Technical Specifications: Includes a table with specifications for various piston and rod diameters, including standard and low friction seals, and lists dimensions and identifiers for accessories like spherical eyes.

Contact Information: Concludes with contact details for HOERBIGER Automatisierungstechnik GmbH, including their address, phone number, fax, email, and website.
