GA47 Steel Change GearBoston 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

For wash-down applications in wet or harsh environments or where sanitary conditions are a factor

14 1/2° PA gears are used extensively because of lower backlash and smoother

Brake coil leads connect directly to motor leads so that power is simultaneously supplied to both brake and motor

a same-hand helix angles must be used

these gears are available only in brass

They withstand extreme temperatures from -400° to +550° F

While 20° PA is generally recognized as having a higher load-carrying capacity

having good hardness

Allows you room to re-bore the ID without damaging the clamp screws

the CUCSFCS has a Hard Chrome bearing insert and a Stainless Steel housing

Note: Because the efficiency of a worm gear drive depends on the lead angle and number of starts on the worm
