Airtac RMH Magnetic Coupling Rodless Cylinder RMH20X800S
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.

The RMH20X800S features a completely sealed magnetic coupling design eliminating external leakage risks. Its innovative piston-embedded magnet system enables direct position feedback without separate sensors. The extruded aluminum body with hardened stainless steel guide rail ensures precision in long-stroke applications while resisting side-load deflection. Requires clean compressed air with 5-40μm filtration.
- Long-span material transfer in cleanroom environments
- Precision glass panel handling systems
- Automated packaging line pusher mechanisms
- Pharmaceutical blister packaging machines
- Solar panel assembly conveyor systems
Installation tip:
Maintain 0.05-0.15mm clearance between magnetic slider and rail surface during alignment.
Use torque-limiting wrench (1.2-1.5N·m) for mounting bolts to prevent rail deformation.
