What are the common types of end mounting methods for gas springs?

Gas springs, also known as lift supports, require secure and precise mounting to perform reliably. The end mounting method determines how the gas spring connects to doors, panels, or equipment, affecting motion, stability, and load handling. Choosing the right end fitting ensures smooth operation, durability, and safety in various applications.

Ball Socket End

The ball socket end is the most common mounting method for gas springs. It features a spherical socket that snaps onto a corresponding ball stud, allowing angular movement during operation. This flexibility reduces stress on both the gas spring and the connected structure, making it ideal for applications requiring smooth pivoting.

• Allows rotation and pivoting, minimizing wear and tear.
• Facilitates easy installation and replacement without tools.
• Commonly used in automotive hoods, tailgates, and furniture lids.

Eyelet End

The eyelet end consists of a circular loop designed to be bolted or pinned to a mounting structure. It provides a rigid, secure connection, making it suitable for applications where rotation is limited or controlled. Eyelet mounts are simple, cost-effective, and widely used in industrial environments.

• Provides a firm, fixed connection to the mounting surface.
• Easy to align and secure with bolts or pins.
• Common in heavy doors, machinery panels, and industrial equipment.

Threaded Stud End

Threaded stud ends have a protruding threaded rod that allows the gas spring to be bolted directly to a mating component. This method provides precise alignment and adjustment options, making it suitable for setups that require exact positioning or occasional replacement of mounting hardware.

• Enables fine adjustment of mounting position.
• Supports easy replacement of end fittings or hardware.
• Widely used in furniture, medical equipment, and machinery applications.

Clevis End

The clevis end features a U-shaped bracket at the gas spring's end, secured with a pin through the mounting structure. This design provides a strong pivoting connection and can handle high loads, making it ideal for heavy-duty or industrial applications where stability and strength are critical.

• Provides a robust pivot point for heavy loads.
• Handles high cycle operation without compromising performance.
• Common in industrial doors, machinery, and large equipment panels.

Bracket or Flange End

Bracket or flange ends feature a flat plate or mounting bracket attached to the gas spring cylinder, which is bolted directly to a surface. This method provides a fixed orientation, offering minimal rotation, and is suitable for installations where precise alignment and stability are required.

• Ensures stable mounting with minimal angular movement.
• Ideal for cabinets, machinery covers, or controlled-motion panels.
• Provides a secure connection for moderate to heavy-duty applications.

Comparison of End Mounting Methods

Understanding the differences between mounting methods helps in selecting the right type for a specific application. The table below summarizes key characteristics:

Conclusion

Selecting the correct end mounting method for gas springs is essential for ensuring smooth motion, durability, and safety. Ball sockets allow flexible rotation, eyelets provide rigid connections, clevis ends handle heavy loads, and bracket or flange mounts offer stable orientation. Understanding these options helps engineers and designers choose the right solution for a wide range of industrial, automotive, and furniture applications.
