The SKF split plummer block housing from the SSNLD line is a solid base component that houses and secures bearings in equipment with rotating shafts. Its split design allows mounting and dismounting without dismantling the shaft, which simplifies plant maintenance. It is used in conveyors, mills, pumps and industrial fans. MR Accesorios Industriales supplies this line with technical advice to select the right variant.

The SSNLD designation is read in blocks: the letters indicate the split plummer block housing with solid base category; the first number identifies the size and the combination of diameters; the NM or MS suffix defines the sealing type and the bearing series it houses. For example, SSNLD 216 NM/MS2 corresponds to a housing for a 16-inch shaft with NM sealing and series 2 bearing, while SSNLD 516-613 NM/MS1 combines two shaft sizes in the same housing. Understanding this logic prevents errors when ordering spare parts.

In Argentine industry, these housings appear in belt conveyors, flour mills, centrifugal pumps, induced draft fans and mixers. Their solid base absorbs combined loads and vibrations typical of heavy equipment. Being split, they adapt to existing shafts without the need to remove pulleys, couplings or complete drives, which reduces downtime in food, cement, mining and aggregate processing plants.

To select the housing, verify the shaft diameter, radial and axial load, and environmental conditions. The NM or MS sealing defines the degree of protection against dust and humidity: choose the most closed one in dirty environments or with frequent washdowns. Check the alignment between housings and the bearing internal clearance during mounting; proper lubrication and progressive tightening of the connecting screws ensure service life. The solid base requires a flat, rigid surface to avoid deformation.

SKF SSNLD housings are interchangeable with other brands that use the same mounting standard and shaft dimensions, although the sealing suffixes and bearing series may vary. Before replacing, compare the complete code, shaft size and locking type. If you have doubts, send a photo of the nameplate or the old housing: at MR Accesorios Industriales we help you identify the right equivalence without compromising equipment operation.
