Standard & Cogged V-Belts

Available2,123 products

These standard and cogged V-belts are single belts that mount to pulleys to transmit power between rotational shafts. The fit of the belt's V-shaped profile in the groove of the pulley and the proper belt tension are key to a drive system's performance. Cogged V-belts have grooves across the width of the belt to dissipate heat. These standard and cogged V-belts are categorized by the dimensions of their cross section and features that impact performance. These category designations are set by the Association for Rubber Products Manufacturers (ARPM) to help with the exchange and replacement of V-belts.

2L Section V-Belts

2L section V-belts are light duty belts for fractional horsepower (FHP) applications. They have a nominal top width of 1/4" and a nominal thickness of 5/32" (actual dimensions may vary slightly). FHP V-belts, identified with an "L," are single belts used on drive systems that are typically operating at 3 HP or less. These V-belts are often used in HVAC equipment and appliances.

3L Section V-Belts

3L section V-belts are light duty belts for fractional horsepower (FHP) applications. They have a nominal top width of 3/8" and a nominal thickness of 7/32" (actual dimensions may vary slightly). FHP V-belts, identified with an "L," are single belts used on drive systems that are typically operating at 3 HP or less. These V-belts are often used in HVAC equipment and appliances.

4L Section V-Belts

4L section V-belts are light duty belts for fractional horsepower (FHP) applications. They have a nominal top width of 1/2" and a nominal thickness of 5/16" (actual dimensions may vary slightly). FHP V-belts, identified with an "L," are single belts used on drive systems that are typically operating at 3 HP or less. These V-belts are often used in HVAC equipment and appliances.

5L Section V-Belts

5L section V-belts are light duty belts for fractional horsepower (FHP) applications. They have a nominal top width of 21/32" and a nominal thickness of 3/8" (actual dimensions may vary slightly). FHP V-belts, identified with an "L," are single belts used on drive systems that are typically operating at 3 HP or less. These V-belts are often used in HVAC equipment and appliances.

A Section V-Belts

A section V-belts are the largest of the classical design belts with a nominal top width of 1/2" and a nominal thickness of 5/16" (actual dimensions may vary slightly). They are used in drive systems that require power transmission of 1 HP or greater.

AX Section V-Belts

AX section V-belts have a classical, cogged design with a nominal top width of 1/2" and a nominal thickness of 5/16" (actual dimensions may vary slightly). Cogged V-belts have grooves across the width of the belt and are identified with an "X." They run cooler than standard V-belts because the cogs allow the belt to bend and flex against the pulley, dissipating heat. They are useful for small diameter pulleys and drives with twists and turns. These V-belts are used in drive systems that require power transmission of 1 HP or greater.

B Section V-Belts

B section classical V-belts have a nominal top width of 21/32" and a nominal thickness of 13/32" (actual dimensions may vary slightly). They are used in drive systems that require power transmission of 1 HP or greater.

BX Section V-Belts

BX section V-belts have a classical, cogged design with a nominal top width of 21/32" and a nominal thickness of 13/32" (actual dimensions may vary slightly). Cogged V-belts have grooves across the width of the belt and are identified with an "X." They run cooler than standard V-belts because the cogs allow the belt to bend and flex against the pulley, dissipating heat. They are useful for small diameter pulleys and drives with twists and turns. These V-belts are used in drive systems that require power transmission of 1 HP or greater.

C Section V-Belts

C section classical V-belts have a nominal top width of 7/8" and a nominal thickness of 17/32" (actual dimensions may vary slightly). They are used in drive systems that require power transmission of 1 HP or greater.

CX Section V-Belts

CX section V-belts have a classical, cogged design with a nominal top width of 7/8" and a nominal thickness of 17/32" (actual dimensions may vary slightly). Cogged V-belts have grooves across the width of the belt and are identified with an "X." They run cooler than standard V-belts because the cogs allow the belt to bend and flex against the pulley, dissipating heat. They are useful for small diameter pulleys and drives with twists and turns. These V-belts are used in drive systems that require power transmission of 1 HP or greater.

3V Section V-Belts

3V section V-belts have a wedge design and a nominal top width of 3/8" and a nominal thickness of 5/16" (actual dimensions may vary slightly). Wedge V-belts, identified with a "V," have a smaller top width and a deeper profile than classical V-belts. This design transfers higher power than classical V-belts of the same size.

3VX Section V-Belts

3VX section V-belts have a wedge, cogged design and a nominal top width of 3/8" and a nominal thickness of 5/16" (actual dimensions may vary slightly). Wedge V-belts, identified with a "V," have a smaller top width and a deeper profile than classical V-belts. This design transfers higher power than classical V-belts of the same size. Cogged V-belts have grooves across the width of the belt and are identified with an "X." They run cooler than standard V-belts because the cogs allow the belt to bend and flex against the pulley, dissipating heat. They are useful for small diameter pulleys and drives with twists and turns.

5V Section V-Belts

5V section V-belts have a wedge design and a nominal top width of 5/8" and a nominal thickness of 17/32" (actual dimensions may vary slightly). Wedge V-belts, identified with a "V," have a smaller top width and a deeper profile than classical V-belts. This design transfers higher power than classical V-belts of the same size.

5VX Section V-Belts
