Description: B345 Classical V-Belt * Reference: B345 * Length: 345 in Inside Length, 348 in Outside Length * Top Width: 5/8 in * Height: 7/16 in * Weight: 3.55 lb * Material: Rubber cushion, polyester cable cord as reinforcement and rubber impregnated woven cotton-polyester fabric * Temperature Resistance: -35C to +70C * Recommended use: Agricultural and Industrial machinery * Recommended pulley diameter: More than 71mm (2-3/4") * Other specifications: Limited Oil resistant, Antistatic, Tolerance Stable V-belts B345 are commonly used in industrial applications because of their relative low cost, ease of installation. The B345 has a V-shape that makes it easier to keep the belt in sheave grooves on fast moving applications. The biggest operational advantage of the B345 V-belt is the wedging action into the sheave groove. This geometry multiplies the low tensioning force to increase friction on the pulley sidewalls improving the power transmission.
