View Full Version : HTD timing belts?

11-21-2009, 01:15 PM
The question is are there typically any local sources? Where should I call/check? I know I can order them online but I am not sure yet what I need and would like an option to go pick one up once I get things together.

The HTD series seems to be really popular I'm sure partly because of how easy it is to make pulleys, but I'm hoping the belts are easy to come by too.

I was thinking maybe automotive timing belt applications? Any joy there? I found several auto timing belts that use a round tooth profile, but are not listed as HTD's, my local NAPA is very patient with me and indulges in most of my hair brained schemes, but I doubt they'll pull dozens of timing belts for me to look at :D

Got my timing belts online, from Stock Drive Products, I believe. I use GT5's. There are several types of timing belts, I seem to remember the GT5's were preferable for precision (CNC drive) applications, though it's been a while and I don't recall the details.

If any one stocks them in your home town, it would be something along the lines of a bearing store or an industrial supply store. And they would only stock a few popular sizes, anything else would be ordered, so you might as well order them yourself.

Yup, like MTNGUN said Stock Drive Products (http://www.sdp-si.com/), probably the best selection of timing belts and pulleys that I can think of.

York is a good supplier, has free design software & catalogs.

SDP-SI does not have the HTD ones. Mostly XL type belts. We were looking for HTD belts for a 4th axis unit we just got.

I bought a 5mm pitch HTD belt recently, it turned out to be Gates brand.

I also made a pair of pulleys for it and used a 3mm ball nose 2 flute slot drill. I imagine a 3.12mm or .125" cutter would also suffice.

So, maybe a bike/skate shop, that is one that hadn't crossed my mind. There is a Gates supplier about 20 minutes from me, I'll give them a call Monday as well...

As usual, thanks for the pointers.
