Gear Shafts

It’s advantageous to cut gear teeth as an integrated feature of a shaft to which a gear would otherwise be assembled. When practical, this eliminates assembly costs of a gear onto a shaft, as well as any eccentricity that could result from the assembling of separate components. Drawing on over 80 years of industry experience, our engineers will work with you to develop gear shaft designs requiring fewer parts and less machining than traditional shaft mounted gears. This typically result in lower production costs as well as a higher precision gear – as forming the gear teeth on a blank that has been machined as an integral shaft feature minimizes the runout of the gear pitch diameter relative to the mounting surfaces of the shaft.

Gear Shaft Experience

Geartronics commonly produces gear shafts that incorporate spur, helical and bevel gears as well as worms for many of our customers that are used in numerous applications. Such components are made from many different materials and include various machined features such as thru-holes, threaded holes, keyways, cutouts, slots and machined squares. We supply parts in hardened or unhardened condition and when required, Geartronics can also finish grind shaft bearing journals to within a .0002”/.0003” tolerance range.

Geatronics has manufactured gear shafts for customers from a number of industries, including:

  • Aerospace
  • Appliance
  • Automotive
  • Consumer Product
