Rotary Bending Testing Machines

Rotating bar bending fatigue tests at various types of specimens with high measurement accuracy and comfortable operation

Rotary bending testing machine are designed for dynamic fatigue tests by Wöhler according to DIN 50113 at specimens like wire, round specimens and rods as well as appropriate components, such as camshafts. Rotary bending testing machines are used in quality and material control. 

Rotary Bending Testing Machine UBM 8

Application

The rotary bending testing machine UBM 8 serves for carrying out fatigue tests according to DIN 50113 at specimens, such as wires, round specimens and rods with bending moments up to about 50 Nm.

Characteristics

  • Table-top device
  • Specimens are loaded by wire rope hoists, generating torsional moments at the specimen by means of an adjustable spring at a lifting system
  • Number of revolutions continuously adjustable between 50 and 3400 rpm
  • Number of revolutions controlled actively
  • Rotation bearing with very low friction

Rotary Bending Testing Machine UBM 9

Application

The rotary bending testing machine UBM 9 serves for carrying out fatigue tests according to DIN 50113 at specimens such as wires, round specimens and rods with bending moments higher than 50 Nm.

Characteristics

  • Stand-alone device
  • Specimens are loaded by wire rope hoists, generating torsional moments at the specimen by means of an adjustable weight at a lifting system
  • Number of revolutions continuously adjustable between 700 and 6000 rpm
  • Safety hood with locking switch to protect the test room
  • When the specimen breaks, the specimen pieces are separated from each other to maintain the fracture pattern
