The NPD pillow block is a mounted pillow block unit with an insert bearing from the SEALMASTER line that MR Accesorios Industriales supplies in Buenos Aires, Argentina. It is used to support rotating shafts in equipment where a compact, self-aligning unit with simple mounting is required. The NPD series covers different shaft sizes and is selected by shaft diameter and locking type. If you need to replace an existing unit, send us the part number on WhatsApp and we'll quote it.

The NPD designation reads as a pillow block series with insert bearing: the letters identify the family and the number that follows indicates the shaft size. For example, NPD-14, NPD-15 and NPD-16 are three different sizes within the same series; NPD-19, NPD-20, NPD-22, NPD-23 and NPD-24 complete the range. The numeric suffix is not a material or sealing code: it is the size reference that must be matched when ordering a replacement.

These pillow blocks are found in belt conveyors, packaging lines, mixers, fans, mills and process lines in food, chemical and materials plants. In Argentina they are common in equipment that runs transmission shafts and where an easy-to-align unit is required. The pillow block housing can be mounted on a baseplate or steel structure with two bolts, and the insert accommodates a certain amount of misalignment from assembly.

To select correctly, first check the shaft diameter and the insert locking type: there are versions with set screws, eccentric collar or taper sleeve. Also check the sealing, because in dusty or humid environments additional protection is advisable. During mounting, seat the housing on a flat surface, tighten the bolts without forcing them and verify that the shaft turns freely. Insert lubrication is done according to the application and the environment.

Regarding equivalents, the SEALMASTER NPD series can be cross-referenced with other pillow block lines with insert bearings of similar sizes, but interchangeability is not automatic: center heights, hole spacing and locking type vary. That is why it is best to compare drawing against drawing or provide the full part number. If you can't find the size, write to us and we'll indicate the compatible alternative.

MR Accesorios Industriales supplies the SEALMASTER line and also manufactures split plummer block housings, ANSI roller chains and pulleys (sheaves). If you need a quote for an NPD-14, NPD-20 or any other size in the series, send the part number on WhatsApp along with the shaft diameter and the application. We'll reply shortly with the quote and the technical data you need for mounting.
