Divide the driven sprocket teeth by the driver sprocket teeth to get the reduction ratio. For example, a 20T driver paired with a 30T driven sprocket gives a 1.5:1 reduction. Match your required output speed and torque to select the correct pairing. If you are replacing an existing sprocket, count the teeth on the worn part or check your machine's documentation.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat taper lock bushing size does this sprocket accept?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eThe compatible taper lock bushing size depends on the specific tooth count variant.
