Airtac RMH Magnetic Coupling Rodless Cylinder RMH20X750S
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 utilizing magnetic coupling technology to eliminate mechanical contact between piston and carriage. Features a stainless steel band seal for contamination resistance and zero-lubrication operation. The anodized aluminum profile ensures corrosion resistance in harsh environments. Includes built-in T-slot for sensor mounting and automatic wear compensation mechanism.
- High-speed pick-and-place systems (electronics assembly)
- Cleanroom automation (semiconductor manufacturing)
- Long-stroke material transfer (packaging lines)
- Precision coating/dosing equipment
- Automated inspection systems with encoder integration
Installation note:
Maintain parallel alignment within 0.2mm/m and use supported rail systems for strokes >500mm.
Magnetic field requires 50mm clearance from ferrous materials. Lubricate guide bearings every 5,000km travel.
