Sprocket Adaptor 20 mm ID x .8" wide. This part has a CNC machined 1/4" half circle cut keyway that fits the 6 mm square keyway (You can also use a Square key) with two set screws along with three 1/4-20 drilled and taped holes to attach the sprocket. Includes the 1/4" x 1/2" dowel pin used as a key.
The three 1/4-20 holes are 1.2" apart with a Bolt Circle Diameter: 1.4"
We have several sizes of sprockets that will bolt to this adaptor.
Make sure the Sprocket hole pattern matches the adaptor.
No Welding and you can change ratios just by changing the sprocket on the same adaptor.
Be sure and order the THREE Socket Head Cap Screws if you need them. A HEX Head bolt will NOT work.
