AirTAC RMH Series: High-Precision Magnetic Rodless Cylinder with Slide Rail

The AirTAC RMH Series is a high-performance magnetic rodless cylinder engineered for applications requiring superior operational accuracy and heavy load capacity. Unlike traditional actuators, the RMH series utilizes a magnetic coupling system between the internal piston and external carriage, eliminating the need for a physical piston rod and significantly reducing the installation footprint.

Equipped with an integrated slide rail, this series ensures high non-rotating accuracy and smooth, stable linear motion. Its isolated design makes it inherently dustproof, while the combination of non-adjustable rubber bumpers and adjustable pneumatic cushioning on both ends guarantees quiet, smooth action even at high speeds.

Key Features:

  • Integrated Slide Rail: Provides high operational accuracy and ensures the body does not rotate during travel.

  • High Load Capacity: Engineered to handle significant loads with stability and precision.

  • Space-Saving Rodless Design: The magnetic coupling (carriage/piston) design offers a compact profile for tight machine layouts.

  • Dustproof Construction: Total isolation between the carriage and piston protects the unit from environmental contaminants.

  • Dual Cushioning System: Features both non-adjustable rubber bumpers and adjustable pneumatic cushioning on both ends for perfected impact relief.

  • Smooth Linear Travel: The carriage slides freely along the main tube, providing consistent performance throughout the stroke.
