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 guidelines:
Maintain parallelism within 0.5mm/m between guide rails. Use mounting brackets at both ends (AXMP20 recommended).
Lubricate with ISO VG32 hydraulic oil. For 700mm stroke applications, install intermediate support at 300mm intervals.
Critical note:
Avoid lateral impact during operation. Magnetic coupling efficiency decreases above 70℃ - install heat shields in high-temperature environments.
Minimum operating pressure must exceed 0.1MPa to maintain magnetic adhesion.
