Split plummer block housings were introduced to make assembly and maintenance easier. These units are made from grey cast iron. They consist of upper and lower housing parts that are screwed together. Every housing can accommodate bearings with different inner diameters and widths. The outside diameter of the bearing is the critical dimension for the housing. Spherical roller bearings are primarily used for split plummer block housings. At higher speeds self-aligning ball bearings can also be used. In order to implement fixed bearings, two additional fixed rings FRB are inserted into the housing. For optimal bearing, the housings are sealed with sealing sets. Here double-lipped seals SC..DS (standard),felt strip gaskets SC..FS, V-ring seals SC..SV, taconite seals SC..TA or labyrinth seals SC..LAare used. All housings are designed so that they can be used for continuous shafts or also for shaft ends. For shaft ends, we recommend closing the housing with an SC..EC cover plate.
