POLY V BELTS
   

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:

 

PH - Fractional Horse Power belt for very light duty applications
PJ - Low cost belt for light duty applications
PK - Designed specifically for the automotive, it is also suitable for Machine Tool drives, etc
PL - Medium duty drive belt covering a wide range of applications
PM - High performance makes this belt unrivalled for heavy-duty applications

Advantages

  • Eliminates belt matching

  • Permits drive design to meet exact power or space requirements

  • Distributes the drive load across the entire belt width

  • Permits cooler running and high drive efficiency

  • Excels on small pulleys at high speeds
