43mm Rubber Robot Wheel for N20 Gear Motors

43mm drive wheel for a compatible N20 motor

This compact robot wheel combines a rubber tyre with an ABS hub. It is listed with a 43mm outer diameter and a fitting intended for a 3mm D-shaped motor shaft.

It can be considered for suitable small robot cars, line-following platforms and educational drive assemblies. Choose it by matching the actual motor shaft and chassis geometry, not the N20 name alone.

Listed wheel specifications

Check shaft fit and chassis clearance

Verify shaft diameter, flat profile, usable shaft length and hub engagement before fitting the wheel. N20 gear motors can differ, and a wheel intended for a D-shaped shaft should not be assumed to fit a round or differently sized shaft securely.

Check the wheel’s width and required chassis clearance with EPRO if those dimensions are important. Do not force the wheel onto an incompatible shaft or apply installation loads through a delicate gearbox.

Rubber provides a traction surface, but grip depends on the floor, wheel loading and operating conditions. This listing does not establish all-terrain performance, a maximum payload or a guaranteed travel speed.

Related mounting and support parts

A suitable N20 motor mounting bracket can secure a matching motor to your chassis. A mini robot ball caster can support the chassis when its height and load suitability match your design.
