MECHANICAL TESTING LABORATORY

Dynaroll has a well-equipped mechanical engineering laboratory that is available to our customers for precise measurements of mechanical characteristics of bearings, other components and assemblies. Much of the equipment used has been developed in-house to meet demanding measurement requirements.

MICROTORQUETM ANALYSIS OF BEARINGS AND PIVOTS
Starting, average, peak-to-peak torque values
Bearing brinelling
Contamination
Raceway misalignment
Retainer drag
Lubricant fill and quality


VOICE COIL TESTING
Bi-directional torque and Kt analysis


RESONANCE MEASUREMENT

Axial, radial (2-mode) measurement of resonance profile over 100Hz to 20KHz.


RUNOUT
TIR and non-repetitive runout (NRR) to 10-7 inches (mm)


LUBRICANT ANALYSIS
Scanning IR


OTHER MEASUREMENTS
Roundness
Surface finish
Hardness
Automated part scanning (reverse-engineering)

Please contact a Dynaroll representative with your measurement requirements. MicroTorque™ and resonance tester are commercially available from Measurement Research, Inc.
