Girth Gear Maintenance - Fixed Plant Maintenance Solutions

However, operation limits for any Girth gear can be quite small, for instance, a girth gear with a diameter of around 7 metres needs to have an axial runout of no greater than 0.35mm. And depending on the face width, it must be running with a temperature differential across the pinion contact surface in the area of no more that 6 to 8 degrees.
