Poly V belts are an endless loop / belt with V shaped ribs that fit perfectly with the V shaped grooves on a pulley / sheave. Each rib is 2.34mm wide so the approx. width on an individual belt will be: number of ribs x 2.34mm.
The "6869PJ / 270J Premium Poly V Ribbed Drive Belt" would be most suitable for applications requiring a sturdy, flexible, and impact-resistant drive belt, specifically designed for use with the J section of the belt.
