The NPD is a mounted pillow block unit that carries a SEALMASTER insert bearing. It is used to support rotating shafts where a compact, self-aligning assembly is needed and mounting is straightforward. The series includes multiple shaft sizes, and the right unit is chosen by shaft diameter and locking method. To replace an existing pillow block, send the part number and we will quote it.
The NPD code identifies a pillow block series with insert bearing. The letters mark the family; the number after them refers to the shaft size. In this series, NPD-14, NPD-15 and NPD-16 are three separate sizes, and NPD-19, NPD-20, NPD-22, NPD-23 and NPD-24 complete the range. That suffix is a size reference only, not a material or seal code, and it must match when you order a replacement.
You will find these units on belt conveyors, packaging lines, mixers, fans, mills and process lines in food, chemical and materials plants. The housing mounts on a baseplate or steel structure with two bolts, and the insert takes up a certain amount of misalignment from assembly.
To select a unit, start with the shaft diameter and the insert locking type: set screws, eccentric collar or taper sleeve. Check the sealing as well, since dusty or humid environments call for extra protection. When mounting, seat the housing on a flat surface, tighten the bolts without forcing them, and confirm the shaft turns freely. Lubricate the insert according to the application and the environment.
For equivalents, the SEALMASTER NPD series can be cross-referenced with other pillow block lines that use insert bearings of similar sizes. Interchangeability is not automatic, because center heights, hole spacing and locking type vary. Compare drawing against drawing or provide the full part number. If you cannot find the size, contact us and we will point you to a compatible alternative.
MR Industrial Accessories LLC supplies the SEALMASTER line and also manufactures split plummer block housings, roller chains and sheaves. For a quote on 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 will reply promptly with the quote and the technical data you need for mounting.

Frequently asked questions
- How do I determine which NPD pillow block size I need?
- The size is based on the shaft diameter where the unit mounts. Send that measurement on WhatsApp together with the NPD part number from the equipment. If you have the full part number, that is even better; we will quote the equivalent unit promptly.
- What sets an NPD pillow block apart from a split plummer block housing?
- The NPD is a pillow block unit with an insert bearing, supplied assembled. A split plummer block housing is mounted on the shaft without dismantling the transmission. They are different solutions, and the choice depends on access and mounting type.
- Can a SEALMASTER NPD be replaced by another brand?
- Sometimes it can, but you need to compare center height, hole spacing and insert locking system. Matching the shaft diameter alone is not enough. Send us the dimensions and we will indicate the compatible alternative.
