Cogged V-belts are available at Bearing King, these belts have a higher coefficient of friction and are more aggressive which makes them a very efficient belt for power transmission.
At Bearing King, we supply a wide range of cogged V-belts engineered for maximum efficiency in high-performance power transmission applications. Designed with precision-moulded cogs along the inner side of the belt, these belts provide improved flexibility, reduced bending resistance, and superior grip compared to standard wrapped V-belts. This makes them an ideal choice for industries requiring compact drives, high speeds, and reliable operation under demanding conditions.
Why Choose Cogged V Belts?
Unlike conventional belts, cogged designs incorporate a specialised profile that increases the belt’s contact area with the pulley. This results in a higher coefficient of friction, delivering more aggressive and reliable power transmission. In addition, the cogs allow the belt to bend more easily around smaller pulleys while dissipating heat more effectively, preventing premature wear.
Key features include:
-
Higher power transmission capacity than standard wrapped belts.
-
Special cog design for improved flexibility and better heat dissipation.
-
Compatibility with small diameter pulleys and high RPM drives.
-
Anti-static, oil and heat resistant properties for safety and longevity.
-
Wide operating temperature range from -25°C to +100°C.
-
Maximum belt linear speed: Classical section up to 30 m/s, Wedge section up to 42 m/s, Narrow section up to 45 m/s.
With these advantages, cogged belts are widely used in applications such as compressors, machine tools, agricultural machinery, industrial fans, and packaging equipment.
Construction and Design
Bearing King’s cogged V-belts are manufactured with durability and performance in mind. They feature:
-
A special fabric layer for added protection.
-
Cushion rubber compounds to absorb shock and vibration.
-
Stabilised polyester cords treated for strength and resistance to elongation.
-
Fibre-filled base compounds for extra grip and dimensional stability.
-
Moulded cogs that improve flexibility, reduce internal stress, and extend service life.
This robust construction ensures that every belt delivers consistent, long-lasting performance in the most challenging conditions.

Cogged Belts vs Poly V Belts
While cogged V-belts excel in power transmission for smaller pulley systems, many customers also explore poly v belts when designing compact drives. A ribbed poly v belt differs by having multiple longitudinal ribs that spread the load evenly across the pulley surface. This design makes poly v belts ribbed highly efficient for small pulley diameters and high-speed applications, while cogged V-belts provide excellent durability and power transfer in higher torque drives.
For many industrial and automotive setups, the choice between a poly v ribbed belt and a cogged V-belt depends on space constraints, required power capacity, and speed. At Bearing King, we supply both solutions, ensuring our customers can select the most effective belt type for their needs.
