RE: Lubrication for Sliding Connection

[Subject Prev][Subject Next][Thread Prev][Thread Next]
When I want a "cheap" sliding connection, I use two layers of 6 mil poly.
It will never get messy and it can be exposed to conditions that would
deteriorate a lubricant.

Subject:	Lubrication for Sliding Connection

Does anybody have a recommendation for lubricating a sliding connection for
a building expansion joint? It's basically an HSS beam sitting on a
stiffened seat with two threaded studs to the u/s of the HSS tightened
finger tight through slotted holes in the seat. I'm looking for a grease to
specify on the top of the seat that will provide a bit of lubrication,
prevent corrosion on the bearing surface, last a long time and not drip onto
the ceiling below. The connection will be inside a building  in Northern
B.C. and should be heated year round.
