Profile: Ram-gear Mfg., Inc. offers machining gear, pinions, shafts and bearing assemblies for pumpjacks. Our products include herringbone gears, double helical gears and helical reducers. We design herringbone gears from .750 & up to 63" in diameter and cut a max DP of 2 & as small as 24. Our helical reducers have a stronger gear case because of the side thrust produced when under a load. We are also involved with turning, milling, treading, drilling, shaping, hobbing and keywaying.
