Spiral Bevel Gears
Spiral bevel gears transmit power smoothly between intersecting shafts, typically at 90 degrees. We manufacture spiral bevel gear sets from raw blanks to matched pairs, with hardened-and-ground teeth for quiet, high-torque operation.

Internal Gears
Internal gears mesh with external pinions inside a compact envelope, ideal for planetary gearboxes and rotary drives. We produce internal gears by gear shaping with controlled concentricity and profile accuracy.

Spline Shafts
Spline shafts transmit torque reliably between rotating components. We produce involute and straight-sided splines by hobbing and grinding, with controlled concentricity between journals, splines, and bearing seats.

Gear Shaft Assemblies
Gear shaft assemblies combine gear teeth and shaft features in a single component, eliminating press-fit joints and improving concentricity and torque capacity. We machine integral gear shafts from alloy steel blanks with full heat treatment support.
