Fast shipping and exact fit

Exactly what I needed for my 3D printer idler pulleys. The 696 size fit perfectly without any modification.

Good value pack

Overall good quality. One felt slightly stiff out of the box but loosened up after a few minutes of use. Rest were perfect.

Perfect for my drone build

These bearings spin incredibly smooth. I used the 685 model for my motor bells and noticed less friction immediately. Great value for the price.

Highly recommended

Quiet operation and seems very durable. I bought the 688 series for my fishing reel and it works like new.

5 FAQ
