Highest quality hydraulic tube bending machine from PBT

Hydraulic bending - the industry workhorse

Small machines and larger systems for bending tubes are part of the equipment of many companies from all kinds of industries. The hydraulic tube bending machine is the most common of the models in many industries. For example, in the automotive , materials handling and aerospace industries, profile bending is indispensable. Hydraulic machines handle both the simplest bending processes and the most complex shaping of large workpieces, in aluminum, copper or stainless steel. For more than 25 years, PBT has developed the expertise and technology to offer a range of hydraulic profile bending machines, along with specialized expansions, tooling and services to support this varied demand.

Tube bending machines of varying complexity

PBT offers a range of profile bending machine models ranging from a compact bending machine to the absolutely high-quality version for demanding bending processes on larger workpieces. PBT also offers a range of manual and digital controls, the application or necessity of which depends on the intended use or the selected model. Regardless of the model, PBT profile bending machines deliver exacting precision and minimal deviations for large batches.

Hydraulic tube benders

PBT's profile bending machines and controls are among the best in the industry. Each of its models produce precise radii and repeat accuracy for square tubing minimizing batch-related deviation:

- Tube bending machine ARKUS12, 7 liters hydraulic oil capacity:

The Arkus12 is the most compact hydraulic tube bending machine in the range and is particularly suitable for forming smaller tubes made of aluminum or steel. It is used where space is limited. Its infinitely variable adjustment of the roller distance during bending allows small radii from 35mm without causing kinks at up to 12 tons of pressure. Thanks to the compact design, the relatively light weight of 540 kg allows transport with a lift truck.

- Tube bending machine BENDO, 18 liters hydraulic oil capacity:

With 20 tons, the tube bending machine Bendo achieves almost twice as much pressure output as the Arkus12. Despite this higher output, the minimum front roller distance of 280 mm is only slightly higher, so that small radii are also possible with a precise bending process. The weight of 1050 kg is also still suitable for transport and placement using a lift truck. Due to its high performance, the Bendo is particularly suitable for industrial and series production.

- Pipe bending machine PBT25, 17 liters hydraulic oil capacity:

The PBT25 is the purely hydraulic tube bending machine for the highest demands. This is supported by the powerful pressure output of 27 tons and a minimum front roller distance of only 200 mm, which is infinitely adjustable up to 1000 mm. In addition, thanks to a roller height of 300 mm, it offers the largest tool holder. Despite this performance and flexibility, the PBT25 is only slightly larger in size and, with a weight of 1150 kg, can still be moved with a lift truck.

Tube bending machines with servo drive

- Tube bending machine PBT35 Servo, 9 liters hydraulic oil capacity:

As the first tube bending machine with servo hydraulics, the PBT35 Servo was a world first and is still an example of high performance with absolute precision. The drive generates 35 tons of pressure, while the distance between the front rollers is infinitely variable from 360 mm to 1400 mm. Accordingly, there is a slightly larger minimum radius here than with the hydraulic tube bending machines. The PBT35 Servo is also logically heavier. 2250 kg make a crane or forklift necessary for transport and placement.

- HELIX Servo tube bending machine, 9 liters of hydraulic oil:

The HELIX Servo is the premium model of all tube bending machines. With a pressure capacity of 65 tons, it offers the highest performance, and delivers the necessary accuracy. It is clearly oriented towards larger workpieces such as support structures made of robust stainless steel. The minimum spacing of the front rollers of 630 mm and the height of all rollers of 500 mm are suitable for these. Nevertheless, as with all models, the X-axis can be positioned with an accuracy of 0.01 mm. Due to its 5500 kg weight, the only transport option for the HELIX Servo is a crane.

More Information

Hydraulic tube bending machine or servo drive?

Customers from all industries can choose between tube bending machines with purely hydraulic or servo drives. Apart from the budget, the decision is a matter of requirements. PBT's hydraulic profile bending machines enable the smallest radii without kinking, so that enormous precision is possible even with a higher pressure capacity of up to 27 tons. However, this is also associated with more oil consumption and maintenance, as well as higher energy consumption. The servo-driven versions, on the other hand, achieve energy savings of about 70 per cent, operate more quietly and cleanly and, at 9 liters of hydraulic oil each, consume almost as much as the most compact hydraulic tube bending machine. Last but not least, the differentiation also concerns the control options. All of the purely hydraulic machines can be operated either manually or via tablet as well as the PC400 control system. The servo drives, on the other hand, required the PC400 control, which is the highest-quality and most advantageous option.

Comprehensive service for every bending machine
