The toppros PowerGrip is a toothed timing belt, also known as a synchronous belt or camshaft belt, with a trapezoidal tooth profile for use in positioning applications. It is made of neoprene for resistance to dirt, grease, oil, and moisture. It has fiberglass tensile cords for strength, durability, and resistance to elongation, and it has a nylon tooth facing for quieter operation and resistance to wear. toppros tooth profile is designed for use with a specific sprocket groove profile. This belt is recommended for use with matching Extra Light (xl) PowerGrip timing pulleys for increased load capacity and improved registration. This PowerGrip timing belt is suitable for use with office machines, machine tools, postage equipment, sewing machines, vending machines, outdoor power equipment, oil field applications, agricultural applications, and wood, paper, sand, and gravel applications.TIming belts have teeth on the underside of the belt that join with the grooves in a rotating pulley to transmit power at a constant speed without slippage. They are made of compounded rubber and are reinforced lengthwise with fiberglass cords for added strength. The belts require minimal re-tensioning and maintenance, no lubrication, and provide quiet operation. Timing belts are used in industrial applications such as agriculture, and printing machinery, and consumer applications such as office equipment, home appliances, .
