Description
ACJ Adjustable Self-Compensating Hydraulic Shock Absorber
1. Delivers superior and smooth deceleration with adaptive resistance adjustment upon load impact, ensuring optimal shock absorption performance.
2. Monoblock outer body features QPQ surface treatment for exceptional corrosion resistance, wear resistance, and ultra-high pressure tolerance. Fully threaded outer body design enables easy installation/alignment and enhanced heat dissipation efficiency.
3. High-hardness stainless steel piston rod provides enhanced impact resistance and corrosion protection, guaranteeing reliable operation in harsh environments.
4. Proprietary oil injection technology stabilizes damping characteristics for consistent shock absorption performance.
5. Compact structural design with industry-leading maximum energy absorption capacity.
6. Utilizes specialized lubricating oil as damping medium, offering stable buffering performance across extended temperature ranges.
Category: Hydraulic Shock Absorbers | Brand: AIRTC | Series: ACJ （Retained key technical terms: QPQ treatment, monoblock structure, heat dissipation efficiency, piston rod, proprietary oil injection, energy absorption capacity. Optimized phrasing for industry readability while maintaining original HTML structure.）
Installation protocol: Mount within ±1° of vertical axis. Perform 10-15 test cycles before final torque setting (18-22N·m). For horizontal installations, maintain oil port orientation upward. Replace desiccant cartridge every 50,000 cycles in humid environments.
