A sheathed belt (kevlar, aramid) is also better at shock loads. So in a clutching operation like drive on a riding mower or snow blower a sheathed belt would be ideal due to the high shock loads involed. Your bare cord belts don't do shock at all well and are more for constant engagement, mainly in stationary electric motor driven applications such as air compressor, blowers, conveyors, and stationary power tools.

A lot of good information, but a few questions remain. I assume that you cant interchange a deep V belt (V series) with a standard V belt (A-E or L series) of the same outside width and circumference? If not how do you determine what the V angle or depth is from the pullies? Is there a difference between a standard A or B belt and a 1/2 or 5/8 automotive belt? What is the difference between a Gates regular and a Green line belt?

[kamalpiyasiri]

Thanks for the video. What is the difference A and LA belt.

In an application that previously had a rubber belt, will replacing with Kevlar improve wear? This is for a whole-house fan.

I want a belt for my k20a engine. 7pk1770 or 7pk1778

[MrSivart]

Ok, how do you determine your belt from an unlabeled pully? No belt came with the machine.
