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:
Prime the buffer with 3-5 manual compressions before mounting.
Adjust damping force while monitoring the "green zone" indicator window - optimal setting achieved when yellow band remains visible during 90% of compression.
Perform torque check (18-22 N·m) on mounting nut every 2,000 operating hours.
