A Poly V-belt is a flat belt made up to form a ring with internal length-wise grooves. The flat section represents the reinforcing component and the length-wise ribs ensure adequate grip by fitting in the grooves of the corresponding pulleys.
Poly V-Belts belts offer high power capacity in a single flexible low stretch belt. The continuous high tensile synthetic cord makes maximum utilization of the face width and ensures a uniform tension through the belt. These belts are highly flexible and hence can be used with smaller pulley diameters to give a lighter and compact drive. There are five sections available in Poly V-Belts namely:
Fractional Horse Power belt for very light duty applications.
Low cost belt for light duty applications.
Designed specifically for the automotive, it is also suitable for Machine Tool drives, etc
Medium duty drive belt covering a wide range of applications.
High performance makes this belt unrivalled for heavy-duty applications.
