The ACA1412-3N features dynamic viscosity compensation technology that automatically adjusts damping force based on operating temperature (-10℃~80℃). Its dual-chamber design separates oil and nitrogen to prevent aeration, maintaining consistent performance in high-cycle applications. The hexagon-shaped adjustment knob allows tool-free tuning even in confined spaces.
- CNC turret tool changers - absorbs indexing impacts
- Packaging machine stoppers - soft-stop for product positioning
- Automated warehouse shuttles - rail end damping
- Die casting machine ejectors - shock reduction
- Robotic palletizers - arm deceleration at home position
Installation guidelines:1. Mount vertically with rod end downward for optimal oil distribution
2. Allow 15mm clearance behind adjustment dial for maintenance access
3. Pre-lubricate threads with Loctite 243 before final torque (18-22N·m)
4. Perform 50 test cycles before load operation to purge air bubbles
