Poly V Belts:

Sections and Nominal Dimensions:

Through its truncated rib design, multi-ribbed belts ensure an outstanding performance at higher speeds on smaller diameter pulleys. This smooth-running belt provides a power capacity.

Poly V belts are available in J, L and M sections. The figure below shows a cross-sectional view illustrating the nominal belt dimensions — rib width and belt height. All these belts will operate in standard pulleys provided the pulleys are manufactured to the DIN 7867 or ISO 9982 standard for the specific cross-section.

Advantages:

*Extremely smooth and cool running.

*Very high power capacity per rib.

*Long life due to extra load-carrying capacity.

*Improved performance on back idlers.

*Smaller drive package.

*Tolerant of pulley groove debris.

How to Measure A Poly V Belt:

    Nominal top width: bb = Nr x Sg, Where: Nr = number of ribs, Sg = pulley groove spacing
