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 notes:
Maintain parallelism within 0.2mm/m between cylinder and guide rail.
Use only non-contact position sensors (recommended gap: 1.5±0.5mm).
Lubricate slider every 500km travel distance with ISO VG32 hydraulic oil.
