|Boston Gear spur
gears are designed to transmit motion and power between parallel
shafts. The different styles offered include spur, gear rack,
pinion wire, stem pinions, and internal gears, and most come
with a selection of bore diameters, keyways, and setscrews
to accommodate a wide variety of application requirements.
They are available in plastic, non-metallic, brass, steel,
and cast iron and are manufactured in a variety of styles,
including plain, web, web with lightening holes, and web
with spokes. Many are available with or without hubs.
Boston Gear manufactures both 14 1/2° and 20° PA,
involute, full-depth system gears. While 20° PA is
generally recognized as having a higher load-carrying capacity,
14 1/2° PA gears are used extensively because of lower
backlash and smoother, quieter operation. Just ask your
CSR which is best for you. And remember that spur gears
and rack are available via our Guaranteed
Same Day Shipment Program.
