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 guidelines:
Mount perpendicular to impact direction with <2° angular deviation.
Allow 25mm clearance for adjustment knob operation.
Pre-lubricate shaft with ISO VG15 oil before initial use.
Perform 10-15 test cycles before full operation.

Precision-engineered hydraulic damper featuring automatic viscosity compensation for consistent performance across temperature variations. The dual-stage sealing system combines metal scraper and rubber wiper to prevent oil leakage. Integrated anti-rotation design maintains alignment during high-frequency impacts.
Typical Applications:
- Robotic arm end-of-stroke deceleration
- CNC turret punch press overtravel damping
- Automated warehouse shuttle braking systems
- Die casting machine ejection mechanisms
- High-speed packaging equipment cam followers
Installation guidelines:
Mount perpendicular to impact direction with <2° angular deviation.
Allow 25mm clearance for adjustment knob operation.
Pre-lubricate shaft with ISO VG15 oil before initial use.
Perform 10-15 test cycles before full operation.
Maintenance:
Check oil level every 50,000 cycles through inspection window.
Rotate adjustment knob clockwise every 6 months to prevent seal hardening.
Replace wiper seal at 500,000 cycles or when surface cracks appear.
