Gear Spur

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.

We can produce  many different gears with a variety of bore sizes, keyways.

Any questions kindly let us know !
