Suggestions on non-standard bearing application

[homebrewdude]

I have rod that must actuate a rotating lever. The interface between the rod and lever must have rolling/sliding contact.

I currently have a clasp and “bearing rod” on the end that interface with the lever.
There will be a limited amount of rotational movement on the “bearing rod”.

Since the assembly is currently designed as low carbon steel, I have been looking at a self-lubricating insert of the “bearing rod”

This insert can not be a full round, probably a 120° window.

15,000 lb max force on the lever.
Low creep
High load
Self-lubricating

I have a PDF file to help explain, where can I upload it?

This sounds like a good application for brgs. provided by igus or some other similar manufacturer. igus link is listed below.

Good Luck!

Self lubricating.
Low creep.
Consider fiber re-enforced thermosetting resin composite bearing materials. As a general rule they do not creep, and a number have enormous compression strength as well as contain various dry lubricants.

High Load.
If you can, design to reduce pressure on the bearing sliding/rolling interface by increasing the actual contact surface area.
