GA80B Cast Iron Change Gear UHMW Bearing Traditional cost effective rigid couplingBoston Gear change gears are used primarily on machine tools to provide different cutting speeds while using a constant speed input. All Boston Gear change gears are manufactured with a double key to accept the compound steel bushings that connect two gears together, allowing them to spin on an intermediate shaft. The change gears we stock range from 20 tooth through 128 tooth gears, in one tooth increments, depending upon the diametrical pitch, for a
