SMR SN series plummer blocks are suitable for general engineering applications where bearings are subjected to moderate loads & speeds & are required to work within a relatively clean and temperate environment.
SN housings are of split type and are equipped with felt seals. For bearing housings where the bearings are to be axially located, suitable locating rings can be used. For use in adverse environments, bearing housings can also be supplied fitted with horizontal labyrinths seals.
