Cogged V-Belts

Cogged  V-Belt Cross Reference Charts

Cogged V Belts, also known as notched belts, are engineered with precision-cut longitudinal grooves along the inner surface. These grooves reduce bending resistance as the belt wraps around pulleys, allowing for smoother flexing, greater efficiency, and improved performance—especially in high-speed or high-torque applications. The reduced bending stress minimizes heat build-up, lowers energy loss, and extends belt life.

Constructed from premium rubber or synthetic compounds and reinforced with high-strength fibers such as polyester, nylon, or Kevlar, cogged belts offer exceptional durability and load-carrying capacity. The notched profile improves grip, reduces slippage, and enhances power transfer efficiency, even under fluctuating loads or challenging operating conditions.

Cogged belts are widely used in automotive engines, HVAC systems, and industrial machinery where precise, efficient, and reliable power transmission is critical. Their combination of flexibility, strength, and thermal stability makes them a preferred choice for compact drive systems that demand consistent performance across varying speeds and loads.
