TR series magnetic coupling cylinders are rodless cylinders that use the magnetic force of permanent magnets to strongly link the outside slide to the inside one. Both of them slide onto a stainless steel tube with two end caps. The high magnetic coupling force due to the use of special permanent magnets allows to move heavy loads. The technical features of this series allows to use them even in the dust environment because they have a different sealing system of the piston then the band rodless cylinders. TR series is equipped with pneumatic cushioning.
