Stabilus 5105SS Gas Spring – Engineering Excellence in Vehicle Suspension

The Stabilus 5105SS is a high‑performance gas spring (hydraulic cylinder) designed for automotive applications, particularly as a rear‑door or trunk lift mechanism. It is engineered to provide smooth, controlled lifting and lowering of heavy loads while maintaining structural integrity and durability under repeated use.

Key Technical Specifications

• Spring Type: Gas‑charged hydraulic cylinder
• Load Capacity: 530 Newton (≈120 lbs)
• Stroke Length: Variable, typically 100–200 mm depending on mounting configuration
• Operating Pressure: Approximately 10–12 bar (145–174 psi)
• Material: High‑strength steel alloy with corrosion‑resistant coating
• End Fittings: Threaded or flanged, compatible with standard automotive lift‑mat assemblies
• Temperature Range: -40 °C to +120 °C (suitable for automotive climates)
• Compliance: Meets ISO 9001 and automotive safety standards

Design Features & Advantages

The Stabilus 5105SS incorporates several design elements that set it apart from conventional lift mechanisms:

1. Compact Geometry: The cylinder’s slender profile allows installation in tight rear‑door spaces without compromising vehicle aesthetics.
2. Balanced Force Distribution: The gas chamber provides a progressive force curve, ensuring that the load is evenly distributed throughout the lift cycle.
3. Low Maintenance: Sealed gas and robust construction reduce the need for lubrication or frequent servicing.
4. High Load Capacity: The 530 N rating supports heavy cargo, making it ideal for commercial vehicles and SUVs.
5. Durability: Corrosion‑resistant coatings and high‑grade steel ensure longevity even in harsh environmental conditions.

Common Applications

The Stabilus 5105SS is widely used in automotive and commercial vehicle fleets for:

• Rear‑Door Lift Systems: Enhancing ease of loading and unloading cargo.
• Trunk & Cargo Bay Lifts: Providing smooth operation for large or heavy items.
• Commercial Delivery Vehicles: Supporting frequent loading cycles with minimal wear.
• Utility Vehicles: Enabling quick access to storage compartments.
• Custom Vehicle Modifications: Used by aftermarket specialists to upgrade lift performance.

Installation & Compatibility

When integrating the Stabilus 5105SS, consider the following:

1. Mounting Points: Ensure that the vehicle’s rear‑door frame or trunk structure can accommodate the cylinder’s mounting flange.
2. Clearance: Verify that the stroke length does not interfere with other components such as hinges or seals.
3. Alignment: Proper alignment is critical to prevent uneven wear and ensure a smooth lift.
4. Compatibility with Lift‑Mat Assemblies: The cylinder is often paired with LIFT-O-MAT® systems, which provide the necessary mechanical linkage.
5. Pressure Regulation: Some installations may require a pressure regulator to maintain optimal gas pressure over time.

Maintenance Guidelines

Although the Stabilus 5105SS is low‑maintenance, periodic checks help maintain performance:

• Visual Inspection: Look for signs of corrosion, dents, or leaks.
• Pressure Check: Use a calibrated gauge to confirm that gas pressure remains within the specified range.
• Lubrication: If the cylinder has external moving parts, apply a high‑quality lubricant as recommended by the manufacturer.
• Seal Integrity: Inspect seals for wear and replace if necessary to prevent gas leakage.
• Operational Test: Perform a full lift cycle to ensure smooth operation and detect any abnormal noises.
