In an earlier post I listed some bearings for Goulds pumps; MODEL LTX = SKF 7310 & SKF 6311, MODEL MTX = SKF 5309 & 6309, MODEL STX = SKF 5306 & 6207, MODEL XLT-X = SKF 5313 & 6313.
Here are a few more. These are Goulds Model 3175 and have raised (letters): (S) = MRC 7313 & 6313, (M) = MRC 7317 & 6317, (L) = MRC 7222 & 6222. These are of course manufacturer installs and could vary if the pumps have been rebuilt. Hopefully I will have some more info in the near future on different types of pumps and will post them when I get them.
