Precision-engineered hydraulic damper with automatic oil compensation system, featuring maintenance-free operation through self-sealing piston design. The chromium-plated piston rod and multi-labyrinth seal structure ensure stable damping force across 500,000+ cycles. Includes adjustable cushioning via integrated bypass valve (pre-calibrated at factory).
- Industrial robot end-effector vibration control
- CNC machine tool automatic door mechanisms
- High-speed packaging equipment stoppers
- Automated warehouse shuttle damping systems
- Press machine ram deceleration
Installation note:
Mount vertically with impact direction aligned to piston axis. Allow 30mm clearance
behind mounting surface for oil expansion. Perform initial 50 test cycles before
full-load operation. Relubricate every 100,000 cycles using ISO VG15 hydraulic oil.
