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 with M8×1.25 mounting bolts (25 N·m torque max). For vertical installations,
ensure oil port faces downward. Perform 5-10 test cycles before full operation.
Re-tighten adjustment knob after 48 hours of initial use.

High-precision hydraulic damper featuring real-time viscosity compensation technology that maintains consistent damping force across temperature fluctuations (-10℃~80℃). The self-lubricating bronze bushing ensures smooth operation under high-cycle conditions (up to 1.5 million cycles). Integrated anti-rotation pins prevent accidental setting changes during operation.
Typical Applications:
- High-speed pick-and-place robot end effectors
- CNC machine tool automatic door mechanisms
- Packaging line product stoppers
- Automated warehouse shuttle dampening
- Elevator car emergency braking systems
Installation Guidelines:
Mount with M8×1.25 mounting bolts (25 N·m torque max). For vertical installations,
ensure oil port faces downward. Perform 5-10 test cycles before full operation.
Re-tighten adjustment knob after 48 hours of initial use.
Maintenance:
Check oil level annually through inspection window (clean with lint-free cloth).
Replace oil every 500,000 cycles or 2 years. Use only AirTAC VG32 replacement oil
to maintain warranty validity.
