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:
Requires torque-controlled tightening (45-50 N·m for M10 bolts) with Loctite 243 threadlocker.
Perform initial 500-cycle break-in period before final damping adjustment.
Maintenance interval: 2 million cycles or 12 months (whichever comes first).

Heavy-duty hydraulic buffer featuring automatic viscosity compensation technology that maintains consistent damping performance across temperature variations (±15% force variance from -10℃ to 80℃). The dual-stage sealing system combines a primary PTFE scraper with secondary NBR wiper to prevent oil leakage. Includes 360° rotatable impact head for misalignment compensation.
Typical Applications:
- CNC machine tool automatic door mechanisms
- Automated warehouse stacker cranes
- Stamping press ejection systems
- Robotic welding cell positioning stops
- Packaging line divert arm dampening
Installation protocol:
Requires torque-controlled tightening (45-50 N·m for M10 bolts) with Loctite 243 threadlocker.
Perform initial 500-cycle break-in period before final damping adjustment.
Maintenance interval: 2 million cycles or 12 months (whichever comes first).
Adjustment procedure:
- Loosen locknut with 17mm wrench
- Turn adjustment screw clockwise to increase damping (max 8 full rotations)
- Test with 3-5 full-stroke impacts between adjustments
- Retighten locknut while holding screw position
