34mm x 6mm Rubber Mini Car Wheel for N20 Gear Motor

The 34mm x 6mm Rubber Mini Car Wheel is a white durable plastic hub with a black high-grip rubber tyre, measuring 34mm outer diameter and 6mm width, with a D-shaft bore designed specifically for N20 gear motor output shafts. This n20 motor wheel uses a D-shaft interface — unlike all other round-bore wheels in StemVolt’s lineup, the D-shaft bore has a flat section that mates with the corresponding flat on the N20 motor’s D-shaped output shaft, mechanically preventing the wheel from spinning on the shaft without relying on set screws or friction alone.

This gear motor wheel’s 6mm body width makes it the narrowest wheel in the lineup — narrower than the 11mm micro RC wheel and the 13-20mm range of larger robot wheels — which suits the compact, lightweight mini robot chassis builds that the N20 gear motor is typically used in. The two-material construction separates structural function from grip function: the white durable plastic hub provides the rigid structure that transfers motor torque, while the black high-grip rubber tyre wraps the outer contact surface to provide traction on smooth floors without the slip associated with hard plastic tyres.

this n20 gear motor wheel’s D-shaft bore strictly requires an N20 motor with a matching D-shaped output shaft — it will not fit round-bore motor shafts or other motor types with different shaft profiles. Explore robotics parts at the StemVolt store.
