Parmax SRP as slide brg to replace Nylatron NSM

[dirtft]

I am looking at Parmax SRP as a possible replacement material for Nylatron NSM slide pads. The application is for slide blocks between ladder sections on aluminum ladders. The slide area is open to the environment and we normally lubricate with white lithium grease. Max pressure would be 1000psi, max velocity 1 ft/sec, contact is with 6061-T6511 aluminum extrusions.

Does anyone have experience working with Parmax SRP as a bearing material, particularly against aluminum?
