Correspond à la description
I use this unit to attach the motor joint to the gripped claw
Bearings were needed for a project using the tooth belt and toothed gears also available from Banggood, one set of gears were bored out and the bearings were inserted to make a guide gear for the project, the end result worked great and the gears with the bearings run really smoothly.
well packed. just as desc.
Not used for long, so no idea yet of long term reliability
