See Fig. 8382 above. The effective number is used tocalculate chain speed. Sprockets are normally furnished with twice the effective number listed. When the actual number of teeth is 24 or more, sprockets for No. 160roller chain may be used. See page C-29 for sprocket data.∆ Non-functional dimension that may vary with the type of cutter used.s Based on maximum hub diameter.E-22
