Gates BX68 Tri-Power Belt, BX Section, BX68 Size, 21/32" Width, 13/32" Height, 71" Outside Circumference

This Gates Tri-Power belt is a power transmission V-belt with a combination of flex and load carrying capacity. 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. Notches molded into the underside create the flexibility needed to fit smaller diameter sheaves while maintaining strength and traction. The belt's edge is machined for even sheave groove contact resulting in less slip and wear. It has a working temperature range of -60 to +250 degrees F to protect the belt from cracking and meets RMA oil and heat resistance standards and static conductivity requirements. Tri-Power belts are part of Gates' V80 matching system, which guarantees that all belts of the same type and size will be more precisely matched than the Rubber Manufacturers Association (RMA) and International Standards Organization (ISO) standards require. The result is even load distribution on multi-belt drives and better wear. This V-belt is suitable for use in all industrial applications in which small sheave diameters are required.

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.
