The NTN SN pillow block with insert bearing is an assembled foot-mounted unit that combines a cast iron housing with an insert bearing, ready to mount on a bedplate or structure. It is used to support rotating shafts in equipment where a compact, self-aligning and easy-to-maintain unit is required. MR Accesorios Industriales sells this line in Buenos Aires, Argentina, with more than 80 years of experience in industrial components.
The SN series designation is read as a size code: for example, SN506, SN507 and SN508 indicate different shaft capacities and housing dimensions. The numbers after the letters SN identify the insert bearing size and the housing size. The SN500 series is the most widespread for drive shafts, while the SN600 covers larger diameter applications. When ordering your housing, send the full part number so we can quote the exact unit.
These housings are used in conveyors, mills, mixers, pumps, fans and process equipment in the food, chemical, cement and aggregate processing industries. In Argentina they are common in feed plants, crushing plants and material handling systems. Their foot mounting simplifies installation on profiles or base plates and allows the shaft to be aligned with normal workshop tolerances.
To select the right SN housing, take into account the shaft diameter, the radial and axial load, and the environmental conditions. The insert bearing comes lubricated and sealed from the factory; check that the sealing is suitable for dust or moisture. During mounting, ensure a flat, clean surface and tighten the mounting bolts in a cross pattern. The self-alignment of the insert compensates for small deviations, but the general alignment of the shaft should still be checked.
NTN SN housings are interchangeable with those of other brands that follow the same dimension standard. If you have another brand's part number, we can indicate the compatible equivalent. We can also quote the insert bearing separately if you already have the housing. Send the part number or the shaft size and we will quote promptly.
