Technical Data:
Keyway symmetry gauge
Used to measure the symmetry of shaft keyways
Keyway width range: 5-28mm
Shaft diameter range: dia.14-110mm
Graduation: 0.01mm
Accuracy: 0.02mm
Flat tip with carbide measuring face

Dimensions:
L=100mm
Body/reference diameter=dia.18mm
Spindle/reference diameter=dia.6.5mm
Flat-tip/reference diameter=dia.2mm

Remark:
Measurement method: measure, turn the workpiece 180deg, and measure again
If a=b the slot is at the center; unequal readings indicate offset/warping
