HEAVY DUTY
Sun Gears for Construction & Heavy Machinery
Travel, hub and planetary drives in mobile equipment can expose sun gears to shock, contamination and high peak torque. Replacement work should begin from drawings or measured mating components.

Application-specific RFQ checklist
| Parameter | What to Specify |
|---|---|
| Duty data | Peak torque, shock events, starts under load, reversals, operating hours and contamination. |
| Geometry | Mating planet and ring gear data, especially for replacement components. |
| Interface | Hub, shaft or spline dimensions plus axial retention and bearing relationships. |
| Risk point | Shock and edge loading can make material, case depth and tooth contact decisive. |
Confirm the whole planetary interface
For mobile drives, tooth strength must be reviewed together with spline or shaft support, lubrication, shock loading and the way the carrier distributes load across the planets.
If the original drawing is unavailable, measure the sun gear together with at least one mating planet and record the ring-gear tooth count, carrier arrangement and any hub or shaft interface.
