Custom Splines

Internal & External Splines

Avon Gear manufactures custom internal and external splines in a variety of materials and size ranges. A spline is a series of teeth (splines) on a drive shaft that mesh with grooves in a mating gear. The surfaces of the two, the spline & the meshed gear, allow smooth transfer of force along a straight line of contact.


We take pride in our quality control measures & often exceed AMGA standards to accommodate the intricacies of high precision splines & gears. Our engineering staff will design custom tooling to provide the required custom spline shaft, gear and shape, engineered to tight tolerances & specifications. Our staff will also help with analysis of new designs & improvements on existing designs.


We offer standard & metric sizes for splines and can custom manufacture splines from a variety of materials. We have experience with different types of splines such as tapered spline shafts, high precision blind internal splines, involute and straight sided splines in a wide range of custom applications.


Internal Splines are made primarily using the gear shaping process, but can be broached as well.
