Learn how to replace a gas spring holder on your tanning bed bench. Step-by-step instructions for ProSun Onyx and similar models, plus common mistakes to avoid.
Quick answer
To replace a tanning bed gas spring holder, first disconnect power, then remove the bench acrylic, unscrew the old holder, install the new one (like the ProSun Onyx 15 minute Gas Spring Holder), and reassemble. The whole job takes about 20 minutes.
When to replace the gas spring holder
If your tanning bed bench no longer stays up on its own or drops suddenly, the gas spring holder is likely worn. This part holds the gas spring in place and can crack or loosen over time. Replacing it restores smooth bench operation and prevents accidental pinching.
Step-by-step replacement process
- Disconnect power and remove bench acrylic: Unplug the tanning bed. Remove the acrylic sheet from the bench by unscrewing the retaining strips or clips. Set the acrylic aside in a safe place. Common mistake: forgetting to unplug first. Always disconnect power before working near the bed.
- Locate and remove the old gas spring holder: Find the gas spring holder attached to the bench frame. It is usually a small metal or plastic bracket. Unscrew the mounting bolts (typically 2-4) and slide the holder off the gas spring rod. Checkpoint: note the orientation of the old holder before removal so you install the new one the same way.
- Install the new gas spring holder: Position the new holder (e.g., ProSun Onyx 15 minute Gas Spring Holder) onto the gas spring rod. Align the mounting holes and tighten the bolts evenly. Do not overtighten. Common mistake: overtightening can crack the holder. Use hand tools only, not power tools.
- Reassemble the bench and test: Reattach the bench acrylic and secure it with the retaining strips. Plug in the bed and slowly raise and lower the bench to verify smooth operation. If the bench still drops, the gas spring itself may be worn and need replacement.
