For the other 10 people out there in need of custom coffee roaster belts, like us with our Probat L12, here’s a source: Hudson Belting.
This is more of a Public Service Announcement than anything. We were desperately looking for a domestic source for the main belt for our Probat A machine for roasting coffee. Or the person operating it! The basic requirements for a coffee roaster are a heating element that gets suitably hot and a mechanism... ...more L12 model. The local custom belt maker was sadly gone, like a lot of old time industrial businesses.
And frankly, Probat Burns site for accessories, support and supplies is basically defunct. They have a shop though. You can find mugs and tshirts there. Uh, great.
I found Hudson Belting through some creative web searches, and they were able to make backup belts for me that are working well. The cost for me was about $45-$65 each.
I ordered endless loop belts as well as ones that separate with a pin. When we received this Probat L12 from a used local source, it had a rather loose all-leather belt that looked really old, and had the hook / pin latch in it. It lasted about 8 years!
Hudson recommended leather belts with a synthetic layer to decrease stretching and increase strength. I ordered a couple of those as well as all leather belts for old times sake.
Our 1990s Probat L-12 measured out as 2030 mm and 20mm wide. It may be different for yours. These fit our L-12 perfectly but I am aware the all leather ones may stretch in time.
Here are the questions they asked to be sure they made the right belts for us.
- How did you measure the belt length?
- How wide are your pulleys on the inside where the belt sits?
- Do you have any adjustment on your machine?
- What is the smallest pulley diameter that the belt goes around?
- Do you want the old school Leather Belt or the newer, much stronger Nylon Core Leather Belt?
- Laced belt with metal hooks and pin OR a glued endless belt?
I was just happy to find a source for drive belts and wanted to share the info, saving someone like me a lot of time.
