Pneumatic Rodless Actuators
Rodless pneumatic actuators provide efficient linear motion while eliminating the need for an external piston rod, making them ideal for applications where space is limited. By utilizing an internal piston connected to an external carriage, these actuators deliver long strokes in a compact footprint while maintaining smooth, accurate movement.
Designed for industrial automation, material handling, packaging, assembly, and pick-and-place systems, rodless pneumatic actuators offer high load capacity, excellent repeatability, and reliable performance in demanding environments. Available in mechanically coupled and magnetically coupled designs, they can be configured with integrated guides, cushioning, position sensing, and mounting options to meet a wide range of application requirements.
Rodless Cylinder Magnetically Coupled
Magnetically coupled rodless cylinders eliminate the external piston rod and replace it with an internal piston embedded with rare earth magnets. The piston is magnetically coupled to an external carriage that wraps around the cylinder barrel. When compressed air moves the internal piston, the magnetic force drags the external carriage along the barrel to move the load. By eliminating the extending piston rod, these cylinders eliminate the dead space required for rod overhang and can perform the same job as a standard cylinder using 50% of the installation space. Because they lack a mechanical slot and sealing band, there is no air leakage, which prevents dust and grease from entering the cylinder and prevents compressed air from contaminating cleanroom or food-grade environments.
Rodless Cylinder Mechanically Jointed
Mechanically jointed rodless cylinders operate using an internal piston driven by compressed air. However, instead of a magnetic coupling, the internal piston is directly, mechanically connected to an external carriage through a slit that runs the entire length of the cylinder barrel. To keep the air inside and contaminants outside, a flexible inner sealing band and an outer dust band run the length of the cylinder. As the piston moves, it forces these bands apart for the mechanical joint to pass through and then they re-seal behind it. This cylinder is lower in overall height and lighter than other models, making them ideal for applications with tight vertical clearances.
