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.）
Maintenance note:
Perform oil level inspection every 50,000 cycles using the built-in sight glass.
Rotate adjustment dial clockwise in 15° increments for increased damping force.
Avoid mounting in orientations exceeding 15° from vertical axis.

The ACJ2550F features progressive damping with automatic oil compensation, maintaining consistent performance despite temperature fluctuations. Its dual-seal structure (NBR + PTFE) prevents oil leakage even under high-frequency operation. The hexagonal adjustment collar allows precise damping force calibration without disassembly.
Typical Applications:
- High-speed press brake tooling protection
- Automated robotic arm end-effector damping
- Packaging machine lid closure mechanisms
- CNC tool changer impact absorption
- Elevator car override buffer systems
Maintenance note:
Perform oil level inspection every 50,000 cycles using the built-in sight glass.
Rotate adjustment dial clockwise in 15° increments for increased damping force.
Avoid mounting in orientations exceeding 15° from vertical axis.
