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 and the meshed gear, allow smooth transfer of force along a straight line of contact.

Rhino Gear makes both internal and external splines in a range of configurations.



  • Inner diameter range: 1” to 34”
  • Diametric pitch range: 3 to 64


  • Outer Diameter Range: ½” to 49” with a max length of 24”
  • Diametric pitch range: 3 to 64
