Gates V-belts are known for their quality and durability, but figuring out what those numbers and letters on the labels mean can feel a bit like cracking a code. Let’s break it down into plain English so you can find what you need without the headache.

What's in a Name? Decoding Gates V-Belt Labels

1. Belt Type

The part number on a Gates Hi Power II and Tri-Power belts usually start with one or more letters, which tell you about the belt’s profile—basically its shape and size. Here are some examples:

AX, BX, CX: These belts have notches (cogs) that are molded during the manufacturing process. It helps make them more flexible and help them grip better. More detail on sizes and cross references on our Cogged V-Belt page.

A, B, C, D, E: These are your standard V-belts with different widths and thicknesses tailored to various power needs. You can find a more detailed breakdown and cross referencing on the Conventional V-Belts Pages

2. Dimension Numbers

Right after the type, you'll see a series of digits. These numbers are super important because they tell you the length of the belt. Here’s what they usually mean:

First few digits: This is typically the inside length of the belt in inches. For example, a belt labeled '68' would be 68 inches long inside.

Digits after a hyphen: If there’s a hyphen followed by more numbers, these might highlight a special feature or a different version of the belt.

3. Special Modifications

- You will sometimes see extra letters at the end. These aren’t just random. They give you clues about any special tweaks or strengths of the belt:

- R: Think 'R' for 'reinforced.' This belt is built to be tougher and can handle more wear and tear.

- L: This stands for 'laminated,' a kind of construction that adds durability.

- S: ‘Set-free’ means you can use the belt without worrying about matching it perfectly with others in multi-belt drives.

Here's an example:

Let’s say you come across a belt labeled AX68. Here’s how you’d read it:

- AX: This is a cogged belt with an A profile, a top width of .5 or 1/2 Inch. Cogged  means it’s designed or notched to be flexible and grip well.

- 68: The belt is 68" inches long on the inside. Which gives the belt an outside diameter of 70".
