STEP Lab has developed systems for static and fatigue torsion testing that combine a compact design with high performance. Its control electronics deliver precise data for testing products such as wires, fasteners, keys and springs.
TM Series torsion test systems are designed to meet the most demanding test requirements. Their compact design fits seamlessly into any laboratory layout, while offering outstanding frame rigidity and alignment. Equipped with STEP Lab's advanced control electronics, these systems are the torsion test solution of choice for the biomedical, automotive, aerospace, plastics, metal materials and fastener sectors.
- Five models: TM040 / TM200 / TM360 / TM540 / TM700 — dynamic torque range from 40 to 700 Nm
- Dual linear guide design — high torsional rigidity and low axial friction
- Direct torque transfer from a brushless motor — a genuine ZERO BACKLASH system with no intermediate transmission
- Adjustable reaction support locking system — fixed or floating operation
- Torque transducers ranging 0.2 – 1000 Nm — superior accuracy across a very wide test range
- Test Center software offers advanced torsion-testing options via dedicated torsion test functions
Key Features
- Torsion cell protection fixture — prevents damage to low-capacity torsion cells during test setup
- Optional preload system — pneumatic drive with manual preload value adjustment
- An additional axial load cell can be integrated to measure the true, accurate preload on the specimen
- Maintenance-free, high reliability and efficiency
- Fast, easy installation
