O-Ring design
O-Ring design
(OP)
I'm designing a tool that needs a o-ring. To let you know, this is something i very very rarely do, O-Ring design
Here's my dilemma - I have a part that has a .673 ID that will travel straight up and down. The part will leave the O-ring seal during the process. Looking through the machinery hand book and other web sites i came up with a size for the O-Ring, groove and shaft
O-Ring -015 11/16OD X 9/16ID
Gland Depth - .056
Groove Width - .094
Diametral Clearance - .004 total
Guess what I'm trying to ask is, does this look correct for the spec's given???

What Pressure????
It makes a very very big difference...
RE: O-Ring design
What is the purpose of the o-ring?
BTW, that is not a good situation for the o-ring. The re-entrant 'edge' of the part will need to be very smooth to minimise wear.
RE: O-Ring design
The part ID does have a Rad lead in.

RE: O-Ring design
When there is no seal contact, there will be no pressure. When the seal makes contact, the pressure will rise. What could it rise to?
The fact that the seal is made and then broken means that the application is dynamic, which again is a major contributory factor.

But now that you mentioned static, that what i was little confused on. Even knowing static and reciprocating have the same diametral clearance.
