[TheForge] Air Cylinder (actuators)

Tue Jan 14 08:23:01 2003

Steve, thanks for this note............I'm figuring my ram is gonna weigh 80
lbs and I was going to use a 2 1/2" cylinder.  I've been off rebuilding
power hammers in northern Maine and am catchin up on 500 e-mails here on my
return.......that's why the late comment.

Ralph

> Most guys run 2 to 2 1/2" cylinders for 50-100 lb hammers.
> A 2.5" cylinder at 100psi has close to 500lbs of force, by itself!. I run
a 100lb head unsing a 2.5" cyl. at 120psi. and it works WELL.
> The limiting factor for most guys is the supply of compressed air. To get
good performance out of either of the above configurations you need at least
a two-stage five HP that'll give you ~90 psi at 18cfm
