I have been working with plastic bearings for about 34 years and specialize in their materials and applications. I would love to hear of your experiences, good or bad , in working with plastic bearings in industrial applications.

All right, let me throw you a question...

Is there a plastic bearing strong enough to use on an excavator or backhoe? Very low speed, high load application, plenty of contaminants around... These could be considered if they were cheap and basically throw away items...

Well,

I will be trying some cast Nylon bushing on my Compact Komatsu excavator. I will post the story as it unfolds...

It's Nylon MOS2 type of material see Cat Nylons Web Site.
