Compact rodless cylinder featuring dual-path sealing system and external cushion adjustment screws for precise motion control. The MDJ20X50-40's unique carriage design eliminates rotational play (≤0.5° deviation) while maintaining 95% energy efficiency. Integrated scraper prevents debris accumulation in harsh environments.
- High-speed pick-and-place automation (3-5 cycle/sec)
- Precision alignment in semiconductor wafer handling
- Vertical lifting mechanisms in packaging lines
- Cleanroom applications (ISO Class 5 compatible)
- Multi-axis coordinate systems requiring minimal backlash
Installation protocol:
Maintain 0.02mm/m alignment tolerance during mounting. For vertical installations,
use counterbalance valves when loads exceed 2kg. Lubricate guide rails every
500km travel distance using ISO VG32 hydraulic oil.
