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 requirements:
Maintain ≤0.2mm/m alignment tolerance during mounting. Use only non-magnetic mounting brackets to prevent interference with magnetic coupling. Lubricate with ISO VG32 turbine oil during initial installation. Requires minimum 5μm filtration.

High-precision rodless actuator using magnetic coupling technology to eliminate external leakage risks. Features dual-guide rail structure for enhanced moment resistance (70N·m radial moment capacity). Integrated T-slot mounting groove allows direct carriage tooling attachment. Compatible with ATEX Zone 2 environments when using non-sparking materials.
Typical Applications:
- Cleanroom automation systems (semiconductor handling)
- Vertical lift mechanisms in packaging machinery
- Precision glass panel transfer systems
- Automated welding equipment positioners
- Pharmaceutical blister packaging lines
Installation requirements:
Maintain ≤0.2mm/m alignment tolerance during mounting. Use only non-magnetic mounting brackets to prevent interference with magnetic coupling. Lubricate with ISO VG32 turbine oil during initial installation. Requires minimum 5μm filtration.
Performance Note:
Achieves 1,500km maintenance-free operation under standard conditions (20℃, 0.5MPa, 50%RH). Stroke repeatability ±0.1mm when using regulated air supply. Not recommended for continuous side load applications exceeding 20N.
