Properly storing a hydraulic and pneumatic cylinder will prevent premature failure of the seals and other wear components. If stored correctly you can get longer life and lower your total cost of ownership.
When a cylinder is out of service and in the store room there are general rules that followed lead to the best performing cylinder. Royal has been asked by a lot of equipment owners what is the best procedure for storing cylinders for an extended period. So here are is what is recommended:
Metal Port Plug
WHAT YOU SHOULD BE DOING
- Always store fully retracted
- Store indoors in a clean, dry space that has minimal temperature changes
- Protect the exposed piston rod, steel, and thread with rust inhibitor oil or grease
- Keep rod threads protected by either storing with pre-installed attachments or covering with protective sleeves
- Apply lubrication grease to any eye/clevis bushing or bearings – especially if they are steel
- Plug ports with metal plugs
- If possible fill hydraulic cylinders with oil on the rod side only before plugging.
