description
- Boston Gear's stem pinions feature small numbers of teeth that are cut integral to the steel shaft. Using a special, enlarged pitch diameter minimizes the undercutting of the teeth. When run with standard stock spur gears, stem pinions increase the ratios normally found in spur gear drives.Please note: Stem pinions are not intended to be operated with each other, with internal gears, or with eleven-tooth spur gears. They will, however, run satisfactorily with all other standard 14 1/2° PA spur gears.
