# HTD 3M and 5M timing belts: standard lengths (105-3M to 1926-3M, 120-5M to 2350-5M) and tooth counts

> What lengths do HTD 3M and 5M timing belts come in, and how many teeth does each length have?

- Category: Hardware › Bearings, rails & motion
- Kind: Standard part
- Basis: PowerGrip HTD length list (PDF hosted on Mercateo): designation, length mm, teeth; teeth x pitch = length on every row
- Page: https://xemstudio.com/objects/htd-3m-5m-belt-lengths/ · JSON: https://xemstudio.com/api/geometry?object=htd-3m-5m-belt-lengths · Plain text: https://xemstudio.com/objects/htd-3m-5m-belt-lengths/sheet.txt

**Exact dimensions.** True size, with no tolerance added.

## Notes

- PowerGrip HTD ordering code is length - pitch - width (for example 280-5M-15 is 280 mm long, 5 mm pitch, 15 mm wide). Lengths below are the pitch lengths in mm and the tooth counts as printed in the list read (113 lengths for 3M and 89 for 5M); teeth x pitch equals the length on every row (checked in the generator).
- Widths the list prints: 6, 9 and 15 mm for 3M; 9, 15 and 25 mm for 5M. It marks some lengths as 'available from stock' in bold, which did not survive the text extraction, so no stock claim is made here.
- The PDF names no publisher on its page; its ordering code is Gates PowerGrip HTD. Contitech, Optibelt and others make the same HTD profile in the same pitch lengths, but only this list was read.
- HTD is a round-tooth profile; a GT2 / GT3 belt is not a substitute. 8M and 14M lengths were not read. No files: belts are lengths.
