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.

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.

Are timing belts and synchronous belts the same thing? I need to
transmit 5 to 7.5 Hp to a parallel 1" shaft at 2K RPM, 1:1 with a motor
about 10" away. I'm just not smart or patient enough to figure out the
correct belt using the graphs and formulas on the suppliers' web pages
while some people intuitively know what belt to use. For various
reasons, I can't use V-belts.

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.
