Spiro Gears manufactures custom splines to exact specifications. Through many years of experience, we have the knowledge and expertise to produce both external and internal spline gears to fit almost any application.
Splines are the ridges or teeth (external spline) on a drive shaft that mesh with an equal number of like ridges or teeth (internal spline) in a mating piece with the purpose of transferring torque from one member to the other.
External splines are manufactured by hobbing or shaping process. Internal splines are manufactured by shaping or broaching or CNC wire cutting methods. Spiro Gears will adopt the right process depending upon the quality & qty requirement by the customer.
