GB99A Cast Iron 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

Ideal for wash down applications in wet or harsh environments or where sanitary conditions are a factor

for a nearly infinite number of ratio possibilities

quietest form of gearing when properly applied

high impact and abrasion

the SNATFB has an eccentric locking bearing insert

Can be mounted vertically or horizontally

Splines in crease disc life because the many con tact points between hub and discs reduce the concentration of stresses encountered with non-splined hubs having only a few contact points
