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 tip:
Mount within 15° of vertical orientation. Perform initial break-in by manually cycling
20 times at 50% load before full operation. Re-torque mounting bolts (18-22 Nm) after
48 hours of use.

The ACJ3650 features progressive damping with automatic wear compensation, maintaining consistent performance despite seal degradation. Its dual-chamber design separates oil reservoir from working chamber, enabling 30% faster response than standard buffers. The visible oil level window and tool-free adjustment knob simplify maintenance. Hardened impact surfaces resist deformation in high-cycle applications.
Typical Applications:
- High-speed press brake ram deceleration
- Robotic palletizer end-of-arm tooling
- Automated warehouse vertical lift modules
- Plastic injection molding ejector mechanisms
- CNC machine tool carriage stopping
Installation tip:
Mount within 15° of vertical orientation. Perform initial break-in by manually cycling
20 times at 50% load before full operation. Re-torque mounting bolts (18-22 Nm) after
48 hours of use.
Maintenance:
Check oil viscosity every 6 months or 500k cycles. Replace seals every 1.5 million cycles
in contaminated environments. Use only AirTAC HLP-32 replacement oil to maintain warranty.
