Description
1. Magnetic coupling rodless cylinder design eliminates mechanical connection between piston and slider, delivering exceptional sealing performance;
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.
Category: Rodless Cylinders | Brand: Airtac | Series: RMH
Installation Best Practices:
Maintain parallel alignment within 0.2mm/m during mounting. Use only non-magnetic mounting brackets.
For full-stroke applications, allow 50mm extra space at both ends for cushion adjustment.
Recommended air filtration: 5μm with auto-drain.

The RMH20X350S features a patented magnetic coupling system that eliminates external seals, preventing leakage contamination in clean environments. Its anodized aluminum construction provides corrosion resistance, while the integrated T-slot mounting system enables multi-position sensor installation. The cylinder delivers 10% higher thrust compared to conventional rodless models through optimized magnetic circuit design.
Typical Applications:
- High-speed pick-and-place systems in electronics assembly
- Precision linear motion in semiconductor wafer handling
- Long-stroke packaging machine actuators
- Cleanroom-compatible automation (ISO Class 5 environments)
- Solar panel production line positioning
- Medical device assembly with magnetic position feedback
Installation Best Practices:
Maintain parallel alignment within 0.2mm/m during mounting. Use only non-magnetic mounting brackets.
For full-stroke applications, allow 50mm extra space at both ends for cushion adjustment.
Recommended air filtration: 5μm with auto-drain.
Critical Notes:
- Maximum side load: 15N (axial), 10N (radial)
- Avoid exposure to strong external magnetic fields (>150mT)
- Minimum operating pressure: 0.05MPa for stable magnetic coupling
- Ambient temperature affects magnetic force – derate 0.5% per ℃ above 50℃
