I'm installing a pipe davit behind a concrete seawall and am trying to decide what sort of grease to use. It is custom built so there are no manufacturer recommendations to reference. (The machine shop has made many similar systems, but didn't provide much guidance.)
The davit is constructed of 4" diameter stainless steel pipe, and consists of a a ground sleeve and a long bent pipe which rotates inside the ground sleeve. The base of the ground sleeve is welded closed, and the davit rotates within the ground sleeve on a stainless steel hitch ball which is welded to the bottom of the bent pipe. There are no bearings. The diameter of the ground sleeve is approximately 1/8" greater than the davit pipe, and there is a zerk fitting on the ground sleeve for renewing the grease. I plan to liberally grease the bottom and sides of the ground sleeve before inserting the davit pipe.
Any suggestions on what type of grease to use? One option is marine trailer wheel bearing grease, but my application isn't subject to the same high speed rotation as wheel bearings.
