Mating planet gears
Confirm the mating tooth count, pitch system and pressure angle rather than identifying the sun gear in isolation.
SUN GEAR PRODUCTS
Standard Sun Gears
External sun gears for planetary transmissions, quoted from the tooth system, mating gear geometry and bore/interface drawing.

Technical specification / ordering data
| Parameter | What to Specify |
|---|---|
| Product form | External sun gear; spur or helical as defined by the planetary design. |
| Pitch system | Module or DP per drawing. |
| Pressure angle | Per mating planet gear / drawing. |
| Tooth count | Defined by the planetary ratio and center-distance geometry. |
| Bore / interface | Plain bore, keyway, spline or other controlled interface. |
| Material / heat treatment | Per drawing and duty requirement. |
| Tooth finish | Hobbed/shaped/ground as required by the drawing. |
| Inspection | Tooth thickness/span/over-pin, runout/profile/lead or other agreed characteristics. |
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
External sun gears for planetary transmissions, quoted from the tooth system, mating gear geometry and bore/interface drawing.
For replacement standard sun gears, confirm the tooth system and mating planet/ring geometry before using outside diameter as a selection reference. Photos help identify the layout, but measured tooth data control the part.
