RMT Series Magnetically Coupled Rodless Cylinder
Features
- Magnetically coupled rodless cylinder structure: No mechanical connection between the piston and the slider, ensuring excellent sealing performance.
- The movement of the piston is transmitted to the external slider through magnetic coupling force. No piston rod is required, saving installation space compared to standard cylinders. The maximum stroke is larger than standard cylinders.
- Both ends of the cylinder are equipped with fixed cushioning devices, ensuring smooth reversing motion without impact and avoiding mechanical damage. External hydraulic shock absorbers can be added for better cushioning effects.
- The piston chamber and the slider are separated to prevent dust and dirt from entering the system, extending the service life of the cylinder.
- Dual guide rod structure provides high guiding precision and can withstand certain lateral or eccentric loads.
