Brass Coupler (2.3-5mm)

The Brass Coupler (2.3-5mm) is a small rigid shaft coupler made of brass that joins a 2.3 mm shaft to a 5 mm shaft. It lets you connect a small motor to an axle, drive shaft, wheel or gear with a different shaft size, with screws holding each shaft firmly in place. It is a simple, solid part for RC models, robots and DIY mechanisms.

Tip: A rigid coupler does not absorb misalignment, so line the two shafts up carefully or the motor bearings will wear quickly; use a flexible coupler when exact alignment is hard. Tighten the screws onto the flat of the shaft if it has one, and add a little thread locker in builds with strong vibration.
