Replacement for Sears Craftsman STD304610 v-belt.
This is a premium quality belt made from a polymer blend of natural rubber and SBR with polyester cords and cotton/polyester blend cover. It has better resistance to heat and oil than less expensive natural rubber belts with cotton cords. Polymer blend belts with polyester cord will stretch less than natural rubber belts. Jason Industrial has been manufacturing v-belts, hose and industrial rubber products since 1958. Trust your application to a well respected name in the industry instead of a no name brand product that costs a few dollars less.
