Hi! good day! I'm sorry if my answer is not informative but I'll try my best to do it right.I don't know what is the hardest wood worldwide but in Philippines I know.The national tree of Philippines is the Nara because,in my an-sister,they say that Nara is a powerful tree,so that's why it was worshiped of pagans,the early Filipinos. Nara tree doesn't broken down even a powerful typhoon encountered this tree, so I think Nara tree is the hardest wood worldwide,but It's just an opinion.Yes your opinion was right! your so clever!I hope you like my answer.Thank you for listening.Have a nice day and MERRY CHRISTMAS AND A BLESSED NEW YEAR!!!!

In the US, hard (sugar) maple has been used for years (and still is) as bearings. It is hard and strong enough to support a lot of weight but porous enough to absorb grease. While being greasable, they can be run dry without serious damage.
