Solid base split plummer block housing

The solid base split plummer block housing is a cast component that houses and secures the bearing on a rigid base, with the particular feature of being split into two halves. This construction allows opening the housing, supporting the shaft with the bearing already mounted, and closing it again without disassembling the assembly or moving the machine from its position. It is selected by shaft diameter, the type and size of bearing it will house, the mounting position, and the load transmitted by the equipment. This subcategory contains 52 listed references, all from SKF.

The series you will find follow a designation logic. SSNHD corresponds to the solid base split plummer block housing line with reinforced sealing, designed for environments with dust or lubricant loss. SSNLD is the solid base variant with standard sealing, the most common in continuous-duty equipment. SSED appears in examples with suffixes such as /MS1 or /MS2, which identify the sealing type and the incorporated accessories. In all three cases, the number following the letters indicates the housing size and the bearing it accommodates, and the final letters refer to the sealing configuration.

Typical use is in plant rotating equipment: belt conveyors, mills, centrifugal pumps, fans, mixers, and transmission shafts. The solid base provides rigidity and absorbs loads better than stamped sheet metal, which is why it is chosen in applications where alignment cannot be lost due to vibration. The two-piece mounting also simplifies maintenance in lines where every hour of downtime matters.

To request a quote we need the complete housing code, for example SSNHD 528, SSNLD 526/MS2 or SSED 513-611/MS1; if you don't have it on hand, the shaft diameter and the bearing it will house are enough. If the housing replaces an existing one, send us the shaft size, the center distance of the mounting holes, and a photo of the old part. With that data we verify the equivalent and provide the corresponding option.
