Professional-grade hydraulic damper featuring automatic viscosity compensation technology that maintains consistent damping performance across temperature variations (-10°C to +80°C). The progressive damping curve effectively absorbs high-energy impacts while preventing rebound, with 15-stage adjustable damping force via precision-machined helical groove system. Corrosion-resistant construction includes IP54-rated seals.
- High-speed press machine ram deceleration
- Automated warehouse stacker crane positioning
- CNC tool changer impact absorption
- Robotic arm end effector stabilization
- Packaging line product stopper mechanisms
Installation guidelines:
Mount vertically with impact direction aligned to piston centerline (±2° tolerance).
Perform initial 50-stroke break-in cycle before final adjustment.
Relubricate every 500,000 cycles using ISO VG22 hydraulic oil.
