N2 gas springs

Product catalog summary
Overview: The document provides comprehensive specifications and guidelines for Pascal N2 gas springs, including models DNK, DNR, DNP, and DNA. It details model differences, usage cautions, and tools for gas charge/discharge, as well as specifications for micro hose systems and adaptors.
Specifications: The document outlines specifications for various gas spring models, including cylinder diameter, initial force, and stroke length. For instance, the DNK model ranges from 3.62 kN to 95.4 kN in initial force. It also covers hose models like DNH-SS and adaptors such as DNH-GA, detailing their dimensions and mass.
Model Differences: Differences between models DNK and DNR are highlighted, focusing on threaded hole size, piping port size, and mounting methods. DNK models have M6 or G1/8 threads, while DNR models have similar variations.
Usage Cautions: Users are advised to avoid interference in the die section for models DNR2400 and smaller and to select appropriate stroke lengths for optimal lubrication and performance.
Flange Types: Various flange types (FC, FS, BK, BL) are described with specific dimensions and mounting instructions. Flange mounting screws are not included, and correct backing and mounting procedures are advised.
Gas Charging: The gas charging pressure ranges from 3.4 MPa to 15 MPa, with specific instructions for different models. Check valves are not mounted at shipment, and specific pressures can be specified to one digit after the decimal point.
Procedures: Instructions for gas charging and discharging emphasize using only Nitrogen (N2) gas and specify the charging pressure range. The document advises on safe procedures to avoid injury and equipment damage.
Tools and Equipment: Necessary tools for gas charging and discharging include Allen key wrenches, flathead screwdrivers, and socket wrenches. The document highlights the importance of preventing debris intrusion.
Safety and Recommendations: Safety precautions include wearing safety glasses during gas discharge and ensuring no gas is charged while the spring is under load. The document advises recording the gas pressure on a label after charging.
Global Network: Pascal Engineering's global locations are listed, including offices and plants in Japan, Asia, America, and Europe, supporting automotive production lines worldwide.
Certifications: The document mentions ISO9001 certification, indicating adherence to quality management standards.
Conclusion: The document serves as a comprehensive guide for selecting and using Pascal N2 gas springs and micro hose systems, with detailed technical specifications and practical usage guidelines.
