The ACA2725-3N features automatic oil compensation technology that maintains consistent damping performance without manual adjustment. Its dual-stage buffering mechanism combines orifice damping and spring return, with hardened piston rod (HRC45-50) for wear resistance. The buffer includes anti-rotation design for stable operation in high-cycle applications.
- Automated assembly line indexing mechanisms
- Cartesian robot end effector shock absorption
- Packaging machine cam follower systems
- Stamping press over-travel protection
- CNC tool changer positioning stops
- Conveyor system end-stop dampening
Installation guidelines:
Maintain minimum 3mm clearance around moving parts. Lubricate mounting threads with LOCTITE 243.
Perform initial 50-cycle run-in period before full load operation. Check oil leakage every 50,000 cycles.
Maintenance: Refill through designated oil port using syringe-type injector (not included). Recommended service interval: 2 million cycles or 12 months in normal conditions. Compatible with synthetic oils meeting DIN51524 standards.
