Zwick’s HB series: 50 to 2500kN

HB servo-hydraulic testing machines from Zwick consist of a testing actuator installed on the upper crosshead. This feature makes the machines highly versatile. The integration of the optional T-slotted platform allows the machines to perform component testing, flexure tests, as well as standard fatigue tests. HB-T machine is a version consisting of an additional torsion actuator for combined compression, tensile and torsion loading.

Key Advantages

The following are the key advantages of the HB servo-hydraulic testing machines:

Different versions of the HB servo-hydraulic testing machines are available with a test load range of 50-2500kN

Can be supplied for 210 or 280 bar system pressure

Standard testing actuator stroke of 100, 250 or 400 mm

Based on requirement, it is possible to connect the load cell to the lower crosshead or piston rod

Adjustable upper crosshead with optional hydraulic crosshead clamping and lift cylinders

Test frame exhibits natural resonance and very high stiffness

Avoids unnecessary flexural stress in the sample, thanks to highly accurate load frame alignment

It is possible to customize the testing system as per the individual requirements of customers, for instance, extensometers, test fixtures, sample grips or testing software
