GSV Series Gas Springs (Body Only)

This gas spring body-only format is used in injection mold tooling and industrial mold-support systems where controlled lifting, damping, or assisted opening is required. Because only the spring body is provided, it integrates into OEM end hardware already specified by the tool builder, reducing redesign effort and assembly time.

• Automotive and appliance mold lifters: Fit the body into a custom lift linkage or cover mechanism to deliver repeatable stroke and load response; the variant supports reliable motion using a wide stroke range (7–125 mm).
• Large press/fixture access hatches: Use for vertical motion aids where consistent initial and maximum forces are needed across service conditions; initial load spans 1,700–117,000 N and maximum load up to 330,000 N.
• Maintenance and retrofit assemblies: The body-only supply allows replacement of the cylinder without rebuilding the entire end-of-assembly, improving uptime while maintaining consistent performance.

The provided product data specifies performance ranges for stroke, loads, and dimensional envelope, but it does not list the steel grade, surface treatment (e.g., nitriding), hardness (HRC), or heat-treatment condition. As a result, material microstructure, wear-resistance vs. toughness trade-offs, and exact hardness claims cannot be stated from the available specifications.

For selection in high-wear or cycling-heavy mold environments, request the detailed material certificate for the cylinder body to confirm the steel grade and the heat-treatment state (e.g., quenched & tempered or surface hardened). When multiple material options exist, engineers should compare: (1) hardness level for wear resistance, (2) toughness for shock loading, and (3) corrosion protection for shop-floor humidity and coolant exposure.

Select the correct gas spring body by matching its outer diameter (D), stroke (S), and L dimension to the available space and the required motion travel in the mold accessory or fixture.

• Outer diameter (D): Choose within 19–195 mm to fit the mount interface and clearance envelope around the cylinder.
• Stroke (S): Select from 7–125 mm based on the required open/close travel of the hatch, cover, or assist mechanism.
• Length (L dimension): Verify the assembled working length envelope using L = 44–360 mm, accounting for end hardware and lever geometry.

Match force needs using the initial load (1,700–117,000 N) and maximum load (2,800–330,000 N) so the mechanism provides the target support throughout the stroke. Tolerance/fit requirements depend on the end hardware interface (not specified in the current data), so confirm the mounting dimensions and any required clearance during integration.
