SINOCONVE Classical Wrapped V-Belt for Industrial Machinery Drives
SINOCONVE classical wrapped V-belts are designed for synchronous power transmission in industrial machinery and pulley drive systems. The wrapped rubber construction supports durable operation, while the molded profile provides positive pulley engagement and reliable friction transmission.
The suitable V-belt depends on the section, length mark, finished length, pulley dimensions, transmitted load, speed, tension method and working environment. Share the existing belt marking or drive information with our team so we can review the application and confirm the correct specification.

Material and application note
Section, Li length, finished length, pulley compatibility, belt tension, load and operating environment should be confirmed before ordering. Service life and transmission performance depend on the selected belt construction and actual working conditions.
Classical wrapped V-belt construction
Wrapped outer construction
The wrapped outer layer is intended to support belt protection and stable contact with the pulley during industrial operation. The exact rubber compound and reinforcement should be confirmed for the application.
Molded V-section profile
The V-shaped section is designed to seat in a matching pulley groove and transfer power through controlled friction. Select the belt section according to the existing pulley profile.
Application-based length selection
The supplied reference uses Li as the length mark and lists different length ranges for each section. Confirm the original belt marking and finished dimensions before replacement.
Why buyers choose a classical wrapped V-belt
Supports industrial power transmission
Classical wrapped V-belts are positioned for pulley-driven machinery where reliable friction power transmission is required.
Offers multiple section choices
K, Z, A, AB, B, BC, C, CD, D, CE, CL, E and F sections can be reviewed according to the pulley groove and required transmission conditions.
Supports replacement identification
The existing section marking, Li length, top width, pitch width, height and pulley dimensions can be checked together to reduce replacement errors.
