This Gates PowerBack belt is a power transmission V-belt for roll-to-roll drives in conveyor applications. It is made of EPDM (ethylene propylene diene monomer) rubber for resistance to weathering, oils, water, and some solvents. Its cords are bonded to the body are strongly bonded to the body of the belt for equal load distribution and reducing bending stress without deterioration of the cord. The belt's flat back provides greater top surface contact with roll and from roll to roll. This V-belt meets RMA oil and heat resistance standards and is suitable for use with live roller conveyor applications.V-belts, also called fan belts in automotive applications, link two or more rotating shafts to transmit power in a drive system. The trapezoidal shape of the belt's cross section wedges into the groove of a similarly shaped sheave or pulley to provide traction and alignment. This wedging action increases as the load increases, providing higher torque transmission and minimal slippage. V-belts are standard for belt-driven power transmission and can be used in single- or multi-belt systems for increased carrying power. They are found in drive systems in the automotive, agricultural, textile, printing, mining, and office equipment industries, among others.Gates manufactures power transmission and fluid transfer components and systems. The company, founded in 1917, is headquartered in Denver, CO.
