Thickness of a PTFE plate against bearing
Thickness of a PTFE plate against bearing
(OP)
I was just curious how one determines the size of a teflon (PTFE) plate to be designed as a sliding support but has to bear serious vertical load.
Any basic info will do. Do these plates crack? Do they crush?

RE: Thickness of a PTFE plate against bearing
Normally the ptfe is only a thin layer and is bonded onto a steel or other structural backing plate. The ptfe then carries direct compression for static loads and then also shear in itself and at the bond interface when sliding movement occurs.

What type of load are you looking at? Most PTFE bearings I've seen have a 1/16" plate bonded to a steel plate. The steel plate is then attached to a larger steel plate to form the upper assembly of the bearing. The bearings I've seen are for bridges where the loads are quite high.
