Mating planet gears
Confirm the mating tooth count, pitch system and pressure angle rather than identifying the sun gear in isolation.
SUN GEAR PRODUCTS
Hollow Sun Gears
Sun gears with through-bores or hollow interfaces for compact coaxial planetary arrangements.

Technical specification / ordering data
| Parameter | What to Specify |
|---|---|
| Tooth geometry | Module/DP, pressure angle, tooth count and any profile shift. |
| Bore | Diameter, fit, keyway/spline if present and axial length. |
| Wall / hub geometry | Section thickness, shoulders and retention features. |
| Mating components | Planet gear and ring gear data. |
| Material / heat treatment | Per application and drawing. |
| Inspection | Bore-to-tooth concentricity and required tooth measurements. |
Selection points
These are the questions to close before production.
Concentricity & runout
Define the datum relationship among gear teeth, bore/spline/shaft and bearing seats.
Duty
Rated and peak torque, speed, reversals, shock and life influence material/process decisions.
Inspection
Agree the report content before production when tooth or interface verification is critical.
Replacement and custom projects
Sun gears with through-bores or hollow interfaces for compact coaxial planetary arrangements.
For replacement hollow sun gears, verify bore fit, bore-to-tooth concentricity and the mating planet/ring geometry together. Photos can show the arrangement, but the controlled measurements determine interchangeability.
