Flat belts are used for high-performance conveying and light-duty power transmission. Smaller pulley applications with wide central distances are where they excel. Flat belts are available in jointed and endless designs and can be used to connect inside and outside pulleys. Leather, rubber, and fabric are typically used to make flat belts. Leather belts have a high coefficient of friction and can transmit more power, making them perfect for flat belts. Many layers of belt material are adhered together with cement to create the necessary belt thickness.
