Product highlights

This MG223T/0.5M motor gear is a 23-tooth pinion manufactured from 40Cr steel to offer improved durability under typical model stresses. It is sized for motors using a 0.5mm module and 2.2mm motor tooth diameter and is retained with two 3x3 set screws into a round motor hole.

Fitting tips: confirm module and shaft dimensions, align the pinion so teeth mesh evenly with the spur, then tighten both 3x3 set screws progressively to avoid skew. Test at low throttle to ensure correct engagement before heavy use.

Durability note: 40Cr construction provides a harder wearing surface to reduce tooth deformation and preserve consistent mesh over longer service intervals compared with softer alloys.

Is 40Cr steel overkill for sport models?

40Cr offers a good balance of toughness and wear resistance; for regular sport use it extends service life without unnecessary brittleness, making it a practical upgrade over softer materials.

How often should I inspect this pinion?

Inspect teeth and set screw tightness after the first few runs and then at regular maintenance intervals, especially after exposure to dirt or heavy loads.

Will this pinion reduce gear noise?

Properly matched and installed pinions can reduce gear noise by improving mesh accuracy; worn or mismatched spur gears are the usual source of persistent noise.
