ANSI simplex sprockets, pilot bore
SKF catalogue simplex sprockets for single-strand roller chains to the American ANSI standard, with a pilot bore for finish boring to the shaft diameter. Fourteen sizes from 25-1 (pitch 1/4") through 35-1, 40-1 and 41-1 (1/2"), 50-1, 60-1, 80-1, 100-1, 120-1, 140-1, 160-1, 180-1 and 200-1 up to 240-1 (pitch 3"), with 6 to 112 teeth depending on size.
How to read the designation: the number without its last digit gives the pitch in eighths of an inch (40 = 4/8" = 1/2", 240 = 24/8" = 3"), the suffix -1 means simplex. One product page = one chain size; choose the number of teeth as a variant (1085 variants in total). Delivery time and price are confirmed on request.
