High output force

Rodless Cylinder: Basic Parameters for Selection

An internal piston connects to an external sliding carriage via mechanical or magnetic coupling;

compressed air drives the piston in a reciprocating motion,

directly propelling the external slider in a linear path,

thereby eliminating the need for an extending piston rod and significantly reducing the overall installation length.

RMS Series Rodless Cylinders

Magnetically coupled type

1. Magnetically coupled rodless cylinder: There is no mechanical connection between the piston and the carriage, ensuring excellent sealing performance;

2. Piston movement is transmitted to the external carriage via magnetic coupling force; eliminating the need for a piston rod results in a more compact installation footprint and a longer maximum stroke compared to standard cylinders;

3. Equipped with both adjustable and fixed cushioning devices at both ends, ensuring smooth, shock-free directional changes and preventing mechanical damage;

4. The piston chamber is isolated from the carriage, preventing dust and contaminants from entering the system and thereby extending the cylinder’s service life.

Key Features

Rodless Cylinder are widely used.

1. Mechanically Coupled Rodless Cylinder (Mechanical coupling; most common type)
The cylinder barrel features a longitudinal slot; the piston is mechanically connected to an external carriage, and a steel strip seals the slot. It handles heavy loads and offers good torsional rigidity, capable of withstanding radial loads. Disadvantage: Slight frictional loss occurs at high speeds.
2. Magnetically Coupled Rodless Cylinder (Magnetic coupling)
The cylinder barrel is fully enclosed with no slots; the piston and carriage are linked via permanent magnetic attraction. It offers a complete seal, making it dust-proof and clean. Load capacity is relatively low, and the magnetic coupling may disengage if the load exceeds the magnetic holding force. Suitable for clean-room environments and light-load applications.
