| 5001085-C1102 5001150-C1100 Shock absorber information sheet | |
| Item | Details |
| Shock Absorber Type | Twin-Tube Hydraulic or pneumatically assisted. Internally, it converts vibration energy through hydraulic damping. |
| Mounting Type | 5001085-1102 (Front Shock Absorber): Typically uses an eye-to-eye or pin-on-eye design to match the mounting bracket at the front suspension point of the cab. |
| 5001150-1100 (Rear Shock Absorber): Uses a coilover style design, including a spring seat and limit block. | |
| Material Composition | Cylinder Block: High-strength seamless steel tubing. |
| Piston Rod: Chrome-plated and precision-ground surface to reduce friction and enhance sealing. | |
| Seals: Made of oil-resistant, high/low temperature resistant polyurethane or synthetic rubber to prevent hydraulic oil leakage. | |
| Operating Temperature | Typically designed for an operating range of -40℃ to +80℃ to meet the all-weather and cross-regional operation requirements of trucks. |

Performance Characteristics
Cushioning Performance: Primarily used to absorb and dampen cab vibrations caused by uneven road surfaces during truck operation, improving driver comfort.
Structural Design: 5001150-1100 is typically a combined spring shock absorber with coil springs, providing stronger support and multi-stage cushioning.
5001085-1102 is mostly a hydraulic cylinder structure.
Material: The cylinder body is made of high-strength steel, and the internal piston rod is precision-machined to ensure sealing and long service life.
Usage and Maintenance Precautions:
1.Pair Replacement: It is recommended to replace coaxial components (such as two front shock absorbers or two rear shock absorbers) simultaneously to ensure balanced damping forces and prevent cab tilting.
2.Check for Oil Leaks: The most common sign of hydraulic shock absorber failure is oil stains on the outside of the cylinder body. If obvious oil leakage is found, replace the shock absorber immediately.
3.Bump Blocks: During installation, check that the matching rubber bump blocks and dust covers are intact. Aging and damage will lead to increased noise.
4.Installation and Tightening: Bolts must be tightened to the specified torque. Too loose a fit will cause abnormal noise, while too tight a fit may damage the bushing.
