Papa G•July 27, 2017
Nice product. But did not use in my project.
Center hole not to specs.
Amazon Customer•October 4, 2015
The center hole was not to specs; I had to drill out the hole a little more to get it to fit on my 4mm shaft.

worked well as expected
Good, compact puley.
The Professor•September 18, 2014
Good pulley with a nice deep groove. This size is about the same diameter as a typical project motor, so works well for compact designs. The centre hole fits tightly on a 4mm motor shaft.
Great Pullies
lancej89•May 7, 2014
These pulleys are very inexpensive and worked well for my project. It would be nice if the description for this item listed more dimensions. Just in case anyone is wondering 25 mm is the pitch diameter for the pulley, the outer diameter is about 29mm.
