mini Gas springs

Product catalog summary

Overview: This document provides comprehensive specifications and guidelines for Pascal's mini gas springs, specifically models DSA, DSD, DNK, DNR, and DSC. It includes performance tables, installation instructions, and safety precautions.

Specifications: The document details various models of mini gas springs, each with specific dimensions, initial force, and maximum side-load capabilities. For instance, model DSC38-25 features a piston rod diameter of 38mm and an initial force of 7.98 kN.

Performance Tables: Performance tables are included for different models, showing initial force and full stroke load at 20°C and 21MPa charge pressure. Adjustments for different pressures (18MPa, 15MPa) are also explained.

Installation Guidelines: Recommendations for installation include using a mount flange for certain models like DNR due to shallow tapped holes. The document emphasizes selecting the appropriate stroke length for optimal lubrication and performance.

Safety and Usage Cautions: The document advises on the correct handling and usage of gas springs, stressing the importance of maintaining the specified charge pressure and avoiding excessive side-loads.

Model-Specific Details: Each model is described with its unique features, such as the sleeve-less construction of the DSC model, which offers high durability but is weaker against side-loads compared to the DSA model.

Contact Information: The document provides contact details for Pascal offices in Japan, the USA, Germany, China, Korea, and Thailand for further inquiries and support.

Safety Precautions:

Do not dismantle, machine, weld, or throw the gas spring into fire due to high-pressure gas risks.
Avoid using the tap hole on the piston rod for lifting the entire die assembly; it is meant for single gas spring handling only.
Ensure the piston rod is evenly loaded across its surface.

Operation and Mounting Guidelines:

Securely mount the gas spring using screws or flanges.
Avoid grinding or welding near the gas spring; if unavoidable, cover it to protect from debris.
Do not operate in temperatures exceeding 70°C.
Minimize side-loads to prevent reduced service life.
Operate within the recommended stroke range to avoid damage.
Mount in lubricant-free areas to prevent oil intrusion and pressure build-up.
Avoid sudden piston release to prevent gas exhaust and cylinder damage.
Exhaust internal gas pressure before disposal.

Product Applications:

Pascal products support automotive production lines globally, including die and mold clamping systems, gas springs, and more.

Global Network:

Pascal has a global presence with offices and plants in Japan, Asia, America, and Europe.

Contact Information:

Headquarters in Itami, Hyogo, Japan, with contact details for regional offices in the USA, Germany, China, Korea, and Thailand.
