Straight-toothed gear / shaft / shaft

Boston Gear's spur gears, which are designed to transmit motion and power between parallel shafts, are the most economical gears in the power transmission industry.

We offer both 14 1/2° and 20° PA (pressure angle), involute, and full-depth system gears. 20° PA is generally recognized as having a higher load carrying capacity; however, 14 1/2° PA gears are used extensively as well. This is because the lower pressure angle reduces change in backlash due to center distance variation and concentricity errors. The 14 1/2° PA also provides a higher contact ratio for smoother, quieter operation.

Boston Gear spur gears are available through our Guaranteed Same Day Shipment from our world class manufacturing center in Charlotte, NC. Many different gears with a variety of bore sizes, keyways, and setscrews are routinely in stock, but if the particular bore/keyway/setscrew combination needed is not readily available, our machining experts can alter any gear and ship it within 24 hours. Just ask!
