About this product
Blue aluminum alloy rigid shaft coupler that joins two shafts of different diameters, with a 5 mm bore on one side and an 8 mm bore on the other. Used to connect a motor shaft to a drive shaft in robots, RC boat propellers and DIY machines. Because it is rigid, the shafts must be well aligned.

Frequently asked questions
Can it compensate for misaligned shafts?
No. Rigid couplers need accurately aligned shafts. For angular or parallel misalignment, a flexible coupler is the better choice.
Can it connect a 5 mm motor shaft to an 8 mm shaft?
Yes, that is the listed connection: 5 mm on one end and 8 mm on the other. Make sure both shafts seat fully before tightening.
