High Accuracy Spur Gear for Electric RC

The Serpent 120021 spur gear combines an 87-tooth count with a 48-pitch profile to suit electric RC cars that need dependable gear engagement. Nylon construction reduces weight while resisting common impacts. Engineers placed a mix of holes across the face so you can reach motor mount hardware without removing the whole gearbox, simplifying ratio swaps and maintenance.

Feature Summary for the Serpent Spur

Long-Lasting Material: Nylon chosen for balance of strength and forgiving failure mode.
Accessible Layout: 12 small holes and 9 larger holes for easier motor access and alignment checks.
Stamped Tooth Count: The number of teeth is visible on the face for quick ratio selection.
Works With Many Kits: Compatible with a broad range of electric RC platforms when used with matching 48P pinions.

Which pinion pitch pairs with this spur gear?

Use 48-pitch pinions with the Serpent 120021 to ensure correct tooth engagement. Mixing pitches will cause poor mesh and accelerated wear.

Any tips for reducing gear noise?

Set a correct mesh and use a light, clean gear grease. Avoid over-tightening motor mounts and inspect for bent shafts or misaligned bearings which often cause noise.

How often should I inspect the spur for wear?

Check teeth regularly after high-impact sessions or long runs. Replace the Serpent 120021 when teeth show rounding, chipping, or consistent poor mesh despite adjustments.
