How belt sizes cross-reference
The same belt can be written two ways. The classical A and B belts are named by inside length in inches; the fractional horsepower 4L and 5L belts are named by outside length in tenths of an inch. A 4L belt is the A belt with 2 inches added for the outside, and a 5L belt is the B belt with 3 inches added. That is why 4L280 and A26 are one belt. A cogged belt (AX, BX, 5VX) is the same section and length as its plain partner and is listed as an equivalent; the plain 4L and 5L belts are lighter duty and do not stand in for it.
V-belt section widths
| Section | Top width | Thickness | Notes |
|---|---|---|---|
| A / AX | 1/2" (0.50") | 5/16" (0.31") | AX is the cogged / raw-edge version |
| B / BX | 21/32" (0.66") | 13/32" (0.41") | BX is the cogged / raw-edge version |
| C / CX | 7/8" (0.88") | 17/32" (0.53") | CX is the cogged / raw-edge version |
| D | 1-1/4" (1.25") | 3/4" (0.75") | Heavy industrial section |
| E | 1-1/2" (1.50") | 1" (1.00") | Extra heavy industrial section |
Frequently asked questions
What is the A-section equivalent of a 4L belt?
A 4L belt and an A belt are the same belt written two ways, both 1/2 inch wide. The A number is the inside length in inches and the 4L number is the outside length in tenths of an inch, which is 2 inches longer. So 4L280 is a 28 inch outside length and the same belt as A26 (26 inch inside length). The 5L and B pair works the same way with 3 inches: 5L280 is B25.
Can a cogged AX or BX belt replace a plain A or B belt?
A cogged belt has the same section and length as its plain partner, so it fits the same sheave, and the table lists AX26 as the cogged equivalent of A26 and as able to replace 4L280. It does not work the other way for free: a lighter-duty plain 4L or 5L belt cannot stand in for a cogged AX or BX belt on a drive that needs it. Match what the drive was built with when you can, and note the difference when you do substitute.
Why do 2L and 3L belts have no A or B equivalent?
Because there is nothing to cross-reference them to. The A and B families start at 1/2 inch wide; 2L is 1/4 inch and 3L is 3/8 inch, so those two are their own sizes and the table shows only their width and outside length.
What do the numbers in a belt code mean?
Classical belts (A, B, C, D) carry the inside length in inches: A26 is 26 inches inside. Fractional horsepower belts (2L to 5L) carry the outside length in tenths of an inch: 4L280 is 28.0 inches. Narrow wedge belts (3V, 5V, 8V) also carry the outside length in tenths of an inch: 5V590 is 59.0 inches, and the X in 5VX590 means cogged. Metric wedge belts (SPZ, SPA, SPB, SPC) carry the datum length in millimetres.
Does this page store my belt sizes or need an account?
No to both. The lookup runs in your browser and nothing is saved when you close the tab. If you want the belt size kept on each unit, so you know what to bring to the next belt change, that is what Equipment Tracker is for.
Keep belt sizes on each unit in Equipment Tracker
Write the belt size on the unit once and it is there on the next service call, on your phone, with or without signal. The core of the app is free on the phone, and every first plan, Pro or Team, starts with a 7-day free trial.
