Telescopic gas spring 400 mm 25 kg – code: M3525400 – Trem

Trem telescopic gas spring M3525400

The Trem telescopic gas spring is a hardware component designed for applications where controlled support is needed in the opening/closing of doors, hatches, and panels. This version is identified by the code M3525400 and is suitable for technical contexts, including use in nautical environments, where the choice of materials and finishes is an important aspect for long-term durability.

The product is made with chrome-plated steel rod with thickness and body coated with epoxy powders. The spring is described as resistant to the marine environment, a useful feature for installations on board and in areas exposed to humidity and salt spray.

Features and construction details

Materials and finish

• Rod in thick chrome-plated steel.
• Body with epoxy powder coating.
• Resistance to the marine environment (as per the manufacturer's description).

Main data of the M3525400 variant

For this specific variant, the following dimensional and reaction data are available:

• Open length: 400 mm
• Body: Ø 19 mm
• Stroke: 160 mm
• Rod: Ø 8 mm
• Reaction (F1): 25 kg
• Eyelet hole: 8 mm

Codes and product identification

• Product code (Trem): M3525400
• SKU: TREM0000071
• Tag: gas-spring

Typical applications

A telescopic gas spring is commonly used as support for opening and holding hinged elements in position. In marine and onboard plant applications, it can be used, for example, on:

• Hatches and lockers.
• Doors of technical compartments or storage.
• Panels for access for inspection and maintenance.
• Covers and internal openings where support is useful during handling.

The choice of the correct spring depends on the installation (geometries, fixing points, weight, and balancing of the hatch/panel). In case of replacement, it is good practice to verify that the data of the existing spring correspond to those of the selected variant.

Advantages in the technical field

• Simpler selection: the presence of dimensional data (open, stroke, diameters) helps to quickly compare the spring with the one already installed.
• Finishes suitable for exposed contexts: chrome rod and body painted with epoxy powders are useful indications for applications in humid environments.
• Installation with eye attachment: the eye hole 8 mm allows pairing with hardware compatible with this size.
• Identifiable spare part: the code M3525400 allows faster reordering and reduces the risk of errors during purchase.

Usage and operational notes

Checks before purchase

For a correct purchase (especially in replacement), it is recommended to check:

• Length with spring open and stroke, comparing them with the available space and the required travel.
• Body diameter and rod diameter, for compatibility with brackets and mounting spaces.
• Eyelet hole, for matching with existing pins/attachments.
• Reaction (F1), to maintain behavior similar to that intended by the project or the original configuration.

General installation instructions

The assembly varies depending on the hardware and the kinematics of the hatch/panel. In general, it is advisable to:

• ensure that the fixing points are solid and properly aligned;
• verify that, during the stroke, the spring does not interfere with cables, pipes, or edges;
• perform an open/close test at the end of installation to check smoothness and clearances.

Note: there is no information available in the provided data about recommended orientation, included accessories, or tightening torques; if necessary, it is advisable to refer to the original configuration or the technical documentation of the system.

Maintenance and nautical context

In a marine environment, it is useful to keep exposed parts clean and periodically check the condition of the fastenings. The product description indicates resistance to the marine environment, but actual usage conditions (sprays, salt, exposure) may vary: regular checks help preserve the functionality of the hardware over time.
