I'm sure we all know what I'm referring to when I say "earless" pillow block but is there a correct nomenclature to ask for? I need earless pillow blocks with Timken type tapered roller bearings, or something else that will handle moderate thrust, with a 1" bore and be permanently lubed.
Are timing belts and synchronous belts the same thing? I need to transmit 5 to 7.5 Hp to a parallel 1" shaft at
I've seen them described as "Tapped Base" See:
I believe that the generic term is "synchronous belt" and "timing belt" is a term that might be applied to automobile use, see:
Nope, never heard of an earless pillow block. Could you be thinking of a cartridge? I've used those a long time ago. Otherwise, deep groove ball bearings come lubed and can handle some thrust. I like the SKF site for bearing info.
Yes, a timing belt is an application for a synchronous belt. At that horsepower, I'd start looking at HTD belts. The Gates downloadable catalog is good. I always use the tables, then upsize some. In a synchronous belt, you still end up with a pretty small belt. Which is one reason I use them. Most recently, I used one on the belt grinder I built for my son because I was using a 1:5 ratio, speeding up the output shaft.
PS. I just downloaded and tried Gates Design Flex Pro software. You have to register, but works slick. Try it.

I've seen "timing belt" used by purveyors of mechanical stuff. The impression I get is that if it's there just to keep things synchronized then it's a "timing belt", but if it's there to transmit serious power then it's a "toothed belt" or "synchronous belt".
Of course, "serious power" in a copier may be ten times lighter weight than a "timing belt" in a heavy diesel engine, but hey -- whatever terminology floats your boat.
In the Texas oil fields it would be "one of them thangs" :-)
