Vee Belt Drive

Vee Belts are probably the most common form of belt drive. They are used in many machines and engines because their wedge shaped cross-section grips the 'V' shaped pulleys and enables much higher loads to be transmitted with less slippage.

Vee Belts are available in a range of sizes labelled as letters - A,B,C,D etc. The size of a belt is determined by measuring its top width and depth and checking against manufacturers' charts. The commonly used ‘A’ size for example, measures approximately 13mm across the top and is 8mm deep whereas the smaller ‘M’ size measures 10mm x 6mm.

Multigroove Vee Belt are available for some specialist applications and are generally more efficient.
