C Type Seat Four Rod Hydraulic Cylinder Usage Method:

Mounting and Installation:

    • Determine the proper location of the four rod hydraulic cylinder in the hydraulic system.
    • Ensure the installation surface is clean and free of debris or contaminants.
    • Align the C-seat with the mounting surface and secure with appropriate bolts or fasteners.

Hydraulic Connections:

    • Connect the hydraulic supply line to the cylinder port, ensuring proper seal to prevent leakage.
    • Follow the manufacturer’s recommendations for the type of hydraulic oil and fill the system accordingly.


    • Activate the hydraulic system and use the hydraulic control valve to control the cylinder movement.
    • Adjust flow and pressure Settings to achieve the desired speed and force output.
    • Monitor cylinder operation for any anomalies or signs of failure.

CType Seat Four Rod Hydraulic Cylinder Maintenance:

Regular Inspection:

    • Perform a routine visual inspection to check for any signs of wear, leakage, or damage.
    • Check seals, tie rods and cylinder blocks for abnormalities and replace worn or damaged parts in a timely manner.


    • Follow the manufacturer’s lubrication interval guidelines and use the recommended lubricant to ensure smooth operation.
    • Lubricate rods and seals to prevent friction and extend cylinder life.

Seal Replacement:

    • Over time, the seals may wear out and require replacement.
    • When replacing seals, make sure they are the correct size and type recommended by the manufacturer.
    • Follow proper procedures to disassemble and reassemble the cylinder during seal replacement.

How To Repair A Hydraulic Cylinder?

Repairing a hydraulic cylinder requires careful attention to detail and knowledge of hydraulic systems. Here is a general guide on how to repair a hydraulic cylinder:

  1. Safety First:
    • Before starting any repairs, ensure the hydraulic system is depressurized and all power sources are disconnected.
    • Use appropriate safety equipment such as gloves and eye protection throughout the repair process.
  2. Identify the Problem:
    • Inspect the hydraulic cylinder to determine the cause of the malfunction or damage.
    • Common issues include leaks, damaged seals, bent rods, or worn-out components.
    • Take note of any visible signs of wear, leaks, or abnormal movement.
  3. Disassembly:
    • Begin by removing the hydraulic cylinder from the equipment or system.
    • Carefully disassemble the cylinder, following the manufacturer’s instructions.
    • Take pictures or make notes during disassembly to aid in reassembly.
  4. Inspection and Cleaning:
    • Thoroughly inspect all components for wear, damage, or signs of contamination.
    • Clean all parts using an appropriate cleaning agent to remove dirt, debris, and hydraulic fluid residue.
    • Inspect the rods, pistons, seals, and cylinder barrels for any defects or signs of excessive wear.
  5. Replacement of Seals and O-Rings:
    • Damaged or worn seals and O-rings commonly cause hydraulic cylinder issues.
    • Replace all seals and O-rings with new ones that match the specifications provided by the manufacturer.
    • Ensure proper alignment and lubricate the seals with hydraulic fluid before installation.
  6. Rod Straightening or Replacement:
    • If the rod is bent or damaged, it may need straightening or replacement.
    • Straighten a bent rod using a hydraulic press or seek professional assistance.
    • If the rod is severely damaged, it may need to be replaced entirely.
  7. Component Replacement:
    • Inspect other components, such as bearings, bushings, and pistons, for wear or damage.
    • Replace worn or damaged components with new ones that meet the manufacturer’s specifications.
  8. Reassembly:
    • Assemble the hydraulic cylinder, following the reverse order of disassembly.
    • During reassembly, apply a thin film of hydraulic oil or grease to the seals and components.
    • Ensure that all connections are tight and properly aligned.
  9. Testing and Inspection:
    • Once reassembled, test the hydraulic cylinder for proper operation.
    • Reconnect the hydraulic system and thoroughly inspect any leaks, abnormal sounds, or irregular movement.
    • Cycle the cylinder several times to ensure smooth and consistent operation.
  10. System Flushing and Fluid Replacement:
  • If contamination was found during the repair process, flush the hydraulic system to remove any debris or contaminants.
  • Replace the hydraulic fluid with a fresh supply, following the manufacturer’s fluid type and quantity recommendations.
