Good quality but tight

Machining is precise but needed a little force to install onto the shaft. Works well once mounted.

Perfect for my robot arm

Fits perfectly on the 5mm shaft. Very smooth rotation and no wobble during operation.

Needs lubrication

Was a bit stiff out of the box, added grease and works well now. Good value for money.
