House bracketed bearing? You COULD fabricate a block
from oak, and grease it. Then captivate it in a steel
bracket which bolts to the building. If you were to do
so, look for Fernco rubber plumbing couplings, to place above
and below the block, to keep water out, and grease in.
On the other hand, if you pour enough concrete to start with,
you shouldn't need the house bracket.
