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 note:
Pre-adjust damping force using torque wrench before operation.
Allow 15mm clearance behind buffer for maintenance access.
Perform 50 test cycles after installation to stabilize oil film.
