HÖFLER Cylindrical Gear Roll Testing Machine

Compact, flexible and highly accurate testing technology

The Höfler Roll Testing Machine R 300 is covering the same component spectrum as the Speed Viper series in terms of axis traversing paths. Wheel components can be tested up to an outside diameter of 300 mm. In conjunction with the optional counter support, shafts up to 800 mm long in extreme cases can be analyzed to determine their running performance and noise behavior.

Compact design with minimal footprint of less than 2 m²
Optimal damping thanks to mineral-cast bed
Workpiece spectrum similar to Speed Viper series
One test machine for gear and shaft components
Available roll testing methods: single flank test, structure-borne noise and angular acceleration test, double-flank test
Direct drives in spindles and test slides
Test speeds up to 2,000 rpm
Machine can be used in the GearLab as well as on the shop floor
