# V-Belt Identification

If you’re looking for the right way to power your business, look no further than Texas Belting and Supply. We have a wide selection of V-belt identification sections depending on your business’s needs. Belt identification ranges from A sections, AX, B, BX, C, CX, D, 2 to 5L, 3V, 5V, 8V, and 3XV, 5XV, and 8XV sections. Each section fits top widths from 1/2” to 1” depending on the section you choose. Our V-belt dimensions are perfect for various applications. V-belt identification is ideal for light-duty, heavy-duty, molded-clogged, wedge, or wedge-clogged applications. Call now with any questions or concerns; we’re happy to help you measure your V-belt so that your machines function properly.

**A Section: (ex. A21)**

Smooth

½” Top Width

To Determine Part Number: Take outside circumference of belt (length measured around outside of belt) and subtract 2. Example: If the belt is 23” in outside length, the part number will be 23-2. A21 is final part number.

**AX: (ex. AX45) Dimensional information will remain the same as above.**

Cogged

½” Top Width

To Determine Part Number: Take outside circumference of belt (length measured around outside of belt) and subtract 2. Example: If the belt is 23” in outside length, the part number will be 23-2. A21 is final part number.

**B Section: (ex. B100)**

Smooth

21/32” Top Width

To Determine Part Number: Take outside circumference of belt (length measured around outside of belt) and subtract 3. Example: If the belt is 103” in outside length, the part number will be 103-3. B100 is final part number.

**BX: (ex. BX80) Dimensional information will remain the same as above.**

Cogged

21/32” Top Width

To Determine Part Number: Take outside circumference of belt (length measured around outside of belt) and subtract 3. Example: If the belt is 83” in outside length, the part number will be 83-3. BX80 is final part number.

**C Section: (ex. C98)**

Smooth

7/8” Top Width

To Determine Part Number: Take outside circumference of belt (length measured around outside of belt) and subtract 4. Example: If the belt is 102” in outside length, the part number will be 102-4. C98 is final part number.

**CX: (ex. CX120) Dimensional information will remain the same as above.**

Cogged

7/8” Top Width

To Determine Part Number: Take outside circumference of belt (length measured around outside of belt) and subtract 4. Example: If the belt is 124” in outside length, the part number will be 124-4. CX120 is final part number.

**D: (ex. D144)**

Smooth

1.25” Top Width

**2L Section: (ex. 2L220)**

Smooth

¼” Top Width

To Determine Part Number: Take outside circumference of belt. OC measurement will align with the final three numbers shown in the part number. Example: If the belt is 22” in outside length, the part number will be 2L220.

**3L Section: (ex. 3L455)**

Smooth

3/8” Top Width

To Determine Part Number: Take outside circumference of belt. OC measurement will align with the final three numbers shown in the part number. Example: If the belt is 45.5” in outside length, the part number will be 3L455. You can also sub these belts with a 3V455.

**4L Section: (ex. 4L560)**

Smooth

1/2” Top Width

To Determine Part Number: Take outside circumference of belt. OC measurement will align with the final three numbers shown in the part number. Example: If the belt is 56” in outside length, the part number will be 4L560. 4L belts can be interchangeable with A and AX belts.

**5L Section: (ex. 5L600)**

Smooth

5/8” Top Width

To Determine Part Number: Take outside circumference of belt. OC measurement will align with the final three numbers shown in the part number. Example: If the belt is 60” in outside length, the part number will be 5L600. 5L belts can be interchangeable with B and BX belts.

**3V Section: (ex. 3V710)**

3/8” Top Width

To Determine Part Number: Take outside circumference of belt. OC measurement will align with the final three to four numbers shown in the part number. Example: If the belt is 71” in outside length, the part number will be 3V710. You can also sub these belts with a 3VX710.

**5V Section: (ex. 5V900)**

Smooth

5/8” Top Width

To Determine Part Number: Take outside circumference of belt. OC measurement will align with the final three to four numbers shown in the part number. Example: If the belt is 71” in outside length, the part number will be 5V900. You can also sub these belts with a 5VX900.
