Default Garage Door Opener: Chain vs. Belt?

I think it was Mike Hartigan who stated:

I think it was "Steve Barker LT" who
stated:

I suppose you could ask the harley davidson people which is better. A chain
or a belt. If they can stand up to 100+ HP, i'd rekon they can lift a
garage door for many years.


I think you're a little confused here. 100+ HP Harley Davidson??

Heh, heh, heh . . . .


Chains are ALWAYS preferred on high-performance motorcycles. With good
reason; to handle 100+ HP, a belt would need to be WIDE.


Also consider a timing chain vs belt in a typical car engine. A belt
needs to be replaced at some prescribed interval, per the
manufacturer. A chain is generally expected to last the life of the
engine.


BUT, those are both HIGH stress applications; especially the car
engine, where the heat cycles are tremendous (from many degrees below
zero to a couple of hundred degrees above zero here in Minnesota
during some parts of the year that will be coming soon). I should
think that a belt that would last 60,000 miles in a car would last
hundreds of thousands of cycles in a garage door opener. If it were
engineered correctly.
