Self-compensating hydraulic damper with precision-machined helical oil grooves and multi-stage buffering chambers. Features automatic viscosity compensation for consistent performance across temperature variations. The hardened piston rod (HRC 45-50) ensures wear resistance in high-cycle applications. Includes anti-rotation design for stable linear motion.
- High-speed pick-and-place robot end effectors
- CNC tool changer impact absorption
- Automated conveyor sorting system stoppers
- Stamping press over-travel protection
- Packaging machine lid closing mechanisms
Installation note:
Mount perpendicular to impact direction with Loctite 243 on threads.
Perform initial 500-cycle run-in period before final torque adjustment.
Check oil compensation every 50,000 cycles - refill with ISO VG15-22 hydraulic fluid.
Avoid side loads exceeding 20% of capacity.
Not recommended for continuous impact frequencies above 120 cpm.
Requires protective boot (optional ACA-BT20) in dusty environments.
