V belts are the modern standard for power transmission in most machines. They allow high speeds and high traction without creating too much pulley load and have a long service life. They have a trapezoid cross section with polyester reinforcement cords along their outer edge. This is a pre-stretched heat-set cord capable of carrying high horsepower loads with minimal stretch over it's lifetime. This belt has a top width of 17mm, an inside circumference of 37.5'' (952.5mm) and an outer circumference of 1021.5mm.
