The SEALMASTER NP series is a pillow block mounted bearing unit that combines a cast iron housing with a spherical insert bearing. It is designed to support rotating shafts in conveyors, fans, mixers and other power transmission equipment where alignment and ease of maintenance are important. MR Industrial Accessories LLC supplies this line to customers across the United States, Canada, Mexico and South America.
The NP code consists of the series prefix and a size number. The number does not directly indicate the shaft diameter; it is a size reference that corresponds to specific housing and bearing dimensions. To confirm the correct size for your shaft, refer to the manufacturer's dimension table or send the complete part number to our team.
These units are used in a wide range of industries, including food processing, material handling, and general manufacturing. The pillow block design allows mounting on a flat surface and provides access to the grease fitting for routine lubrication. When selecting an NP unit, consider shaft diameter, radial and axial loads, and the presence of dust, moisture or washdown conditions. Proper sealing and alignment between units help reduce premature wear.
The insert bearing is secured to the shaft with set screws, and the spherical outer ring allows for initial misalignment. Installation requires a clean shaft and proper tightening of the set screws. Lubrication should follow the manufacturer's recommendation, typically a lithium-based grease. Regular inspection of the sealing and grease condition extends service life.
SEALMASTER NP units can be interchanged with other brands that follow the same boundary dimensions, such as SKF, FAG or NTN, provided the shaft diameter, bolt hole spacing and center height match. If you have an existing part number from another brand, send it to us and we can suggest a compatible SEALMASTER NP model.

Frequently asked questions
- What does the NP designation mean in SEALMASTER housings?
- NP is the series of pillow block housings with insert bearing. The number that follows is a size reference, not a direct shaft diameter. To determine the exact dimensions, send us the complete code and we will provide the data.
- How do I know if an NP housing is compatible with my machine?
- Check the shaft diameter, the distance between base bolt holes, and the center height. With those dimensions, we can confirm whether the NP model fits or suggest an alternative.
- What lubrication do these housings need?
- Lubrication depends on the application and insert type. A lithium-based grease is commonly used, but always follow the manufacturer's recommendation. Contact us if you need guidance.
