There is no problem with the product, but I had a hard time choosing the item. I did not know the number of belt groove parts. I ordered it as a single but it was a double. Even though there is only one image, I would like to enhance the product image.
I bought it in a propaganda claim that it can be used immediately after arrival, but there is no set screw processing when attached. If you look at the review there is similar writing. I thought that it was very unkind.
I tried looking for various things but it was saved because the finished goods were on sale. (It was inexpensive for additional machining.) I think that it was the best if I could specify the push screw of the split pin. I installed it on a motor but it seems to be usable without problems.
