The MDD20X20S features a space-saving dual-rod design with enhanced lateral load capacity (30% higher than single-rod models). Its modular construction allows multi-position stops through optional magnetic rings (D-M9N series). The hardened stainless steel rods resist side loads up to 15N·m, making it ideal for precision alignment tasks. Requires 5μm filtered air and monthly re-lubrication in high-cycle applications.
- PCB board clamping/positioning in electronics assembly
- Multi-stage press tooling alignment systems
- Glass panel transfer mechanisms with intermediate stops
- Automated screwdriving stations requiring Z-axis stability
- Pharmaceutical blister packaging alignment guides
Installation tip:
For vertical mounting, use counterbalance valves (AC2000 series recommended).
Maintain 0.5mm minimum clearance between rods and external fixtures.
Align guide rails within ±0.1mm parallelism for optimal performance.
