Product catalog summary

Overview

This document relates to the ISO 6020/2 standard, which governs hydraulic cylinders used in industrial and mobile applications. It establishes requirements for design, dimensions, performance, testing, and quality assurance to ensure interchangeability and reliability.

1. Scope and Application

The standard applies to single-acting and double-acting hydraulic cylinders with specified bore sizes and stroke lengths. It defines dimensional and functional characteristics to ensure compatibility across systems.

2. Technical Specifications

Dimensions: Nominal bore sizes, rod diameters, stroke lengths, mounting types, and port dimensions are standardized for interchangeability.
Materials: Recommended materials for cylinder components are specified to withstand hydraulic pressures and environmental conditions.
Performance Parameters: Maximum operating pressures, speeds, temperature ranges, and load capacities are defined to ensure safe and reliable operation.

3. Design and Construction

Design guidelines include sealing systems to prevent leakage, rod protection mechanisms, cushioning features, and mounting arrangements. Emphasis is placed on robust construction to enhance durability and operational reliability.

4. Testing and Quality Assurance

Pressure Testing: Hydrostatic tests verify structural integrity under specified pressures.
Leakage Tests: Procedures detect internal and external leakage to ensure sealing effectiveness.
Dimensional Checks: Critical dimensions are verified to maintain interchangeability and compliance.

5. Marking and Documentation

Cylinders must be marked with identification codes, manufacturer details, and performance ratings. Accompanying documentation provides traceability and evidence of compliance with standards.

6. Recommendations and Best Practices

Proper installation and maintenance procedures are recommended to maximize cylinder lifespan.
Use of compatible hydraulic fluids and contamination avoidance are emphasized.
Periodic inspections and criteria for seal and component replacement are advised.

7. Tables and Data Summary

The document includes tables listing standard bore sizes, rod diameters, stroke lengths, mounting dimensions, and pressure ratings to aid in selection and design integration.

Additional Observations

The source document appears partially corrupted or unreadable in sections, limiting extraction of some detailed data. However, the summary reflects typical content and structure of ISO 6020/2 and similar technical documents from manufacturers like CMB S.r.l.

Manufacturer and Compliance Information

The cylinders comply with relevant European and international standards, ensuring quality and safety. Manufacturer contact details and support information are provided for technical assistance.

Critical Highlights

Requirements: Adherence to dimensional tolerances, pressure ratings, and procedural steps is mandatory.
Parameters: Defined operating ranges for pressure, temperature, and load must be respected.
Limitations: Operational constraints under specific environmental conditions are noted.
Good Practices: Routine maintenance, proper installation, and use of recommended fluids are essential for longevity.
