Herber 350RL

Our bestseller. A tube bending machine made for advanced bending.


Herber presents a larger machine in Herber’s esteemed RL concept. The Herber 350RL is a Right-Left machine for up to 40 mm OD that was developed in Sweden in close cooperation with leading customers in advanced tube bending. The 350RL sets a new standard in advanced tube bending in terms of automation, flexibility, user-friendliness and productivity on pipe diameters up to 40 mm. The 350RL is the most productive machine of its kind on the market today! The Herber 350 RL is available with “integrated automation” where the machine itself is responsible for loading, bending and laying down the finished product. Simply a smart solution for easy automation and higher output!
