B40 Standard V-Belt

B40 Classical V-Belt is still the most practical, economical and dependable belt for most industrial drives. Innovations have failed to displace the need for classical section belts. Bando's constant improvements in materials, design and manufacturing methods help Power King keep pace with industry's ever increasing demands for long, trouble-free belt service. The bias cut, rubber impregnated fabric cover is woven for super flexibility and friction resistance. To protect the belt's inner components, the tough, long wearing cover is fully oil and heat resistant. Ultra high strength polyester cords assure fatigue resistance and length stability. Each cord is chemically treated to bond to the insulation and compression sections, welding all components together for long service life. Insulation section is designed to protect and support the tensile cords to the compression section so the belt components can't separate. The compression section is specially compounded for flexibility to reduce heat build up while bending around sheaves. This design gives a cooler running, longer lasting belt. The compression section provides firm support to the tensile cords, so an equal load is transferred to all tensile members for uniform load carrying capability
