Hey Joe, I don't have a part number, but it is my understanding guys routinely duplicate that adjustment screw by taking a similar hardened bolt, cutting the head end off to length and grinding the tip to match the worm gear it runs in.
You can probably match the bearing at a local industrial supplier. I never buy OEM bearings for any brand, I always use my local guy to duplicate them for a lot less money.
