Although if you have phosphor bronze bushes, they should be soaked in oil as they absorb the oil and this leaches out during operation..aka self lubricating.
All the rage appears to be going to the silicon synthetic greases although low viscosity mineral greases should suffice. The grease holds the oils in suspension and releases it in operation. Since the mechanicals are at low speed synthetic grease should do ok as advised by timken:
