Hydraulic Cylinder Storage 101

When purchasing hydraulic cylinders for your equipment, proper storage and maintenance are essential considerations in the performance of these cylinders on your equipment.

RAM Industries values collaborative relationships with our OEM customers. We stand behind the quality of our products and aim to provide seamless integration of our cylinders onto your equipment.

Three factors can maximize cylinder condition during storage.

1. External Corrosion Protection

RAM Industries provides maximum corrosion protection for cylinders through our two-part polyurethane paint. The paint provides external protection with short storage times in dry rooms at a constant temperature. Non-painted cylinder and part surfaces are protected using corrosion-protecting oil during assembly.

2. Internal Preservation

Every RAM hydraulic cylinder is hydraulically tested using petroleum-based oil. After testing, the oil film remains inside the cylinders, providing short-term internal corrosion protection. The line connections are closed after the test with secure plugs.

3. Inspection and Maintenance

Cylinders that require more than six months of storage, regularly scheduled inspections and maintenance are recommended.

  • Every 6 weeks rotate hydraulic cylinders that are stored horizontally by 90 degrees to prevent damage to the seals.
  • Inspect and coat the cylinder surfaces with corrosion protection oil.
  • Inspect and lubricate spherical bearings.
  • Inspect and lubricate fitting surfaces or mechanical interfaces.
  • Extend and retract the hydraulic cylinder several centimeters to prevent the seals from bonding. 

Properly storing and maintaining your cylinders helps ensure maximum cylinder performance and prevent issues during installation.

RAM is committed to providing full-service solutions.  Engineering support is available in the final assembling and testing when fitting cylinders on new equipment. The engineering team can also provide troubleshooting for unique challenges that may arise when installing cylinders.

The RAM team is committed and responsive to the needs of our customers.
