Description: A57 Classical V-Belt • Reference: A57 • Length: 57" Inside Length, 59" Outside Length • Top Width: 1/2" • Height: 5/16" • Weight: 0.36lb • 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 A57 are commonly used in industrial applications because of their relative low cost, ease of installation. The A57 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 A57 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.
