How to Choose the Best Mechanical Gas Springs
Understanding Force Requirements
Selecting the correct force for a mechanical gas spring is paramount to its effective operation. Gas springs are rated in pounds (Lb) or Newtons (N), indicating the pressure they exert. For lighter applications like small cabinet doors or toy box lids, a lower force such as the Moicstiy 20N (4.4lb) strut is typically sufficient. Conversely, heavy-duty applications such as RV Murphy beds or truck tonneau covers demand significantly higher forces; for instance, the ARANA unit provides a robust 200 Lb (889 N) of pressure. Users report that misjudging this specification can lead to lids that either slam shut or are impossible to close, highlighting the need to accurately weigh the item the spring will support and potentially factor in leverage.
Considering Length and Compatibility
The extended and compressed lengths of a gas spring dictate its suitability for a specific installation. The extended length is measured from the center of each end fitting when fully open, while the compressed length is when fully closed. For example, the Vepagoo ML9945 offers a 10-inch extended length, suitable for many standard toolboxes or access panels, whereas the SUSPA C16-04270 extends to 17.1 inches, offering a greater range of motion for larger lids. It's crucial to ensure both lengths align with the available space and desired opening angle of your application. Some products, like those from JR Products, also specify their exact compressed length, which is important for ensuring the lid closes fully without obstruction.
Material Quality and Durability
The construction materials of a gas spring directly impact its longevity and performance, especially in varying environmental conditions. The Moicstiy struts, for instance, are described as being made from copper, iron, and plastic, with a chrome-plated surface. This combination typically offers a balance of strength and corrosion resistance for indoor or sheltered outdoor use. For applications exposed to harsher elements, such as marine environments or truck toolboxes, looking for robust finishes and sealed units is advisable. While not always explicitly detailed, the quality of seals and rod finishes, often found in industrial-grade units, contributes significantly to preventing gas leaks and maintaining consistent force over time.
Pros & Cons
Moicstiy 7.3 Inch (185mm) Gas Struts Spring Shocks Lift Support, Gas Props Lid Support for Cabinet Toy Box RV Camper Bed Cupboard, 2 Pack(20N/4.4lb)
Pros
- Features a silent opening mechanism, enhancing user experience in quiet environments.
- Versatile design suitable for a range of lighter applications including cabinets, RV beds, and toy boxes.
- Constructed with copper, iron, and plastic materials, indicating a focus on durability for its intended use.
Cons
- Lower force rating (4.4lb) limits its application to very light lids, potentially insufficient for heavier items.
- Maximum opening angle of 100 degrees might not provide a full vertical lift for all cabinet designs.
Vepagoo ML9945 10 inch 45 Lb/200N Gas Shocks Struts Lift for Truck Pickup Tool Box Storage Lid Door, Set of 2
Pros
- Provides a substantial 45 Lb (200N) of force per shock, suitable for heavier toolboxes and doors.
- Advertised as a 'Universal Strut' with common ball socket end fittings, simplifying replacement or new installations.
- Widely applicable across automotive, industrial, marine, and household sectors, demonstrating broad utility.
Cons
- The 10-inch extended length may be too short for applications requiring a wider opening or greater lift.
- Lack of specific material details beyond 'universal strut' means durability can only be inferred from use.
20 inch 200 LB Gas Prop Struts Shocks, 20" 889 N Gas Spring Lift Supports for Heavy Duty RV Murphy Bed Truck Trailer Cap Tonneau Cover Floor Hatch Trap Door
Pros
- Exceptional 200 LB force capacity, making it ideal for extremely heavy-duty applications like Murphy beds and large hatches.
- Extended length of 20 inches provides significant lift and opening range for substantial lids.
- Explicitly designed for demanding scenarios, ensuring reliable support where standard struts fail.
Cons
- Its very high force can be excessive for lighter lids, potentially causing difficulty in closing or damage.
- The product description explicitly states 'No Brackets,' requiring separate purchase and potentially adding complexity to installation.
Common Mistakes to Avoid
Underestimating Force Requirements
A common pitfall is selecting a gas spring with insufficient or excessive force. Users frequently misjudge the actual weight of a lid, leading to either a lid that still feels heavy and won't stay open, or one that springs open with too much force. For instance, attempting to use a Moicstiy 20N (4.4lb) strut on a heavy RV bed designed for a ARANA 200 LB unit will result in failure to support the load. Always measure the lid's weight and consider the leverage point before selecting a force rating.
Ignoring Extended and Compressed Lengths
Another frequent error is overlooking the precise extended and compressed lengths. A gas spring that is too long will prevent a lid from closing fully, while one that is too short will not allow the lid to open to its desired height or angle. The SUSPA C16-04270 with its 17.1-inch extended length will offer a different range of motion compared to the JR Products GSNI-5000-20 at 10 inches. Always measure the desired open and closed positions to ensure compatibility.
Forgetting Mounting Hardware
Many mechanical gas springs, especially those for heavy-duty applications, are sold without mounting brackets. The ARANA 20 inch 200 LB strut, for example, explicitly states 'No Brackets' in its description. Assuming that all necessary hardware is included can lead to installation delays and additional costs. Always confirm if end fittings and brackets are part of the package or if they need to be sourced separately, ensuring they match the ball socket or eyelet specifications of the chosen spring.
