UL 94: Oil-impregnated sintered bronze?

UL 94: Oil-impregnated sintered bronze?

UL 94: Oil-impregnated sintered bronze?

(OP)
Dear All,
We are designing a product that will likely incorporate oil-impregnated, sintered bronze worm gears. The product may require compliance with once of the UL-94 ratings. However, I can't find any such gears with a UL-94 rating.

Questions:
1. For UL-listed products, are oil-impregnated, sintered bronze worm gears required to be UL-94 rated?
2. If so, where can I find such gears?

Thank you

UL94 is flammability ratings of PLASTIC materials
