The problem solver! Super II® V-Belts are the solution to the constant and costly problem of replacing ordinary V-Belts on troublesome drives. Specially formulated fiber loaded EPDM rubber compounds, engineered fabrics and high modulus polyester cord offer greater strength, longer life, better heat dissipation and higher efficiencies than best in class wrapped V-Belts. The unique CNA (central neutral axis) cord placement positions the strength of the belt lower on the pulleys to maintain stability and prevent roll over. The raw edge construction results in more efficient power transmission and reduced energy loss. Timken Belts Super II® V-Belt, Heavy Duty, A Section, 1/2 in Top Width, 93 in Outside Length, 11/32 in Thickness, -50 to 250 °F, 1 Band, EPDM/Fabric, Polyester Reinforced
