Linear bearing-acetal copolymer radiation protection

[Lady55]

I have a linear roller way bearing that will be used in a radiation environment, 3.5x10^7 Rads (life exposure), this linear roller way, as well as most brands, have end plates that are made with acetal copolymer, this material can only withstand 10^4-10^5 Rads before breakdown. The end cap facilitates recirculation of the bearings. There is not a SST end cap available for this model roller way and the versions with SST end caps do not have the load capacity I need.

Does anyone have any suggestions on how I can protect the acetal copolymer end caps?

Dupont are the manufaturers of Delrin (acetal copolymer), have you tried to contact them for help.

Im not sure where you are based, but i know who to contact at the manufacturing site in Dordrecht Holland if its any help.
