The Robot Wheel 70mm x 20mm for DC Gear Motor is a plastic hub with rubber grip tyre, measuring 70mm outer diameter, 20mm width, and 6mm center shaft bore, designed for standard DC gear motor robot car and DIY project builds. This robotics wheel is the fourth 70mm variant in StemVolt’s wheel lineup and the only 70mm wheel pairing a 6mm DC gear motor bore with a mid-width 20mm body — the two narrower 70mm variants (8mm and 13mm) are designed for BO motor shafts, while the widest 70mm variant (40mm) also uses a 6mm bore but provides maximum traction at nearly double this wheel’s lateral footprint.
The gear motor wheel 20mm width suits chassis designs where 40mm is too wide for the motor bracket clearance but a 6mm gear motor shaft is required — a situation that arises frequently when builders use compact 4WD chassis intended for BO motors but upgrade to DC gear motors without redesigning the chassis bracket spacing. The 70mm gear motor wheel’s rubber grip tyre provides confirmed floor traction on smooth surfaces, and the 70mm diameter delivers the same ground clearance and linear speed per RPM as all other 70mm variants regardless of width.
The 20mm width of this dc gear motor wheel 70mm also matches the body width of the 50mm DC gear motor wheel and the 95mm × 20mm wheel in the range — giving builders a consistent lateral footprint option across three different diameters when designing multi-wheel chassis. Available from StemVolt, offering quality robotics parts and DIY kits at competitive prices. This 70mm wheel 6mm bore is ideal for DC gear motor robot car builds.
