Wrapped V-belt vs Cogged V-belt – How to Choose?

Wrapped V-belt vs. Cogged V-belt – How to Choose?

When used in combine harvesters, the choice between a wrapped V-belt and a cogged V-belt depends on the operating conditions and performance requirements of the drive systems.

Wrapped V-belts are well-suited for heavy-duty and harsh field operations. Their fabric-wrapped construction provides excellent impact resistance, wear resistance, and anti-slip properties. This makes them ideal for handling sudden load changes caused by varying crop density, frequent starts and stops, and dusty environments. They are typically recommended for drives where stability and durability are the top priorities.

Cogged V-belts are designed to deliver higher power transmission efficiency and better heat dissipation—essential for combine harvesters operating for long hours under high load. The cogged structure increases belt flexibility, reduces bending stress, and allows reliable operation on smaller pulleys. These belts are particularly suitable for applications requiring high-speed operation, consistent power output, and reduced operating temperatures.

In summary, for combine harvesters:

Wrapped V-belts are preferred where impact resistance and anti-slip performance are critical.

Cogged V-belts are the better choice for systems demanding good heat dissipation and high power transmission over extended harvesting periods.
