Airtac RMH Magnetic Coupling Rodless Cylinder RMH25X350S
2. Piston motion is transmitted to external slider via magnetic coupling force, eliminating piston rod requirements. Requires 30% less installation space than standard cylinders while achieving 50% longer stroke lengths;
3. Integrated adjustable cushioning with fixed buffer devices at both ends ensures smooth direction reversal with near-zero impact, effectively preventing mechanical wear. Optional external hydraulic shock absorbers available for enhanced damping performance;
4. Isolated piston chamber design creates physical separation from slider mechanism, blocking particulate contamination to extend operational lifespan;
5. Precision-guided rail system ensures ±0.1mm repeat positioning accuracy with anti-rotation stability, supporting radial loads up to 650N.

High-precision rodless cylinder using magnetic coupling technology to eliminate external leakage points. Features zero-piston-rod design for space-saving installations and reduced maintenance. Integrated T-slot along the body allows flexible sensor mounting for position feedback. The double-sealed magnetic slider ensures stable force transmission even in contaminated environments.
- High-speed pick-and-place automation systems
- Cleanroom semiconductor handling equipment
- Precision coating/spraying machinery
- Pharmaceutical packaging lines
- LCD panel transfer mechanisms
- Automated test equipment (ATE) positioning
Installation note:
Maintain 0.05mm/m alignment tolerance during mounting. Use only non-magnetic mounting brackets.
For full-stroke applications, reduce operating pressure to 0.6MPa max to prevent magnetic decoupling.
