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 note:
Maintain parallelism within 0.05mm/m during rail mounting. Use only non-magnetic mounting screws (stainless steel recommended). For vertical installations, implement pneumatic lock valves for fail-safe operation.

Compact rodless actuator using non-contact magnetic coupling technology, eliminating external leakage risks while maintaining smooth linear motion. Features integrated guide rail for enhanced lateral load capacity (max 30N) and aluminum alloy construction with hard anodized surface treatment. Includes built-in magnet for position sensing compatibility.
Typical Applications:
- High-speed pick-and-place systems in electronics assembly
- Precision material handling with limited vertical space
- Cleanroom automation (no particle generation)
- Multi-axis gantry systems requiring compact actuators
- Packaging machinery with frequent reciprocation cycles
Installation note:
Maintain parallelism within 0.05mm/m during rail mounting. Use only non-magnetic mounting screws (stainless steel recommended). For vertical installations, implement pneumatic lock valves for fail-safe operation.
Maintenance cycle:
Relubricate every 500km of travel or 6 months (whichever comes first). Replace scraper seals every 2 million cycles in dusty environments.
