Roller Shear Machine

Home » Roller Shear Machine

The Roller Shear Machine is used to determine the resistance to compression fatigue of flexible cellular polyurethane using dynamic roller compression test.  The Roller Shear Machine fatigues a specimen dynamically with a constant force deflecting the material both vertically and laterally.  It has been used for many years in the foam industry to determine the percentage loss in thickness.
