The SEALMASTER NPMH is a mounted unit that pairs a sealed insert bearing with a cast iron housing. It supports rotating shafts where alignment, contaminant protection and straightforward installation matter. MR Industrial Accessories supplies this series for power transmission applications in industrial plants.
The NPMH code identifies a pillow block series that uses an insert bearing. The number that follows, such as in NPMH-20R, gives the shaft diameter in inches or millimeters, depending on the variant. The R at the end specifies the insert configuration and its locking method. When selecting a code, consider both the shaft diameter and the load type.
Typical applications include conveyors, belts, elevators, mixers, mills and process equipment. In dusty or humid environments—food, cement, mining and aggregate processing plants—these units are common. They also appear in industrial fans and centrifugal pumps that need rigid, removable support.
For selection, review radial and axial loads, rotation speed and sealing type. The insert generally features labyrinth seals or rubber contacts that hold grease in and keep dust out. During mounting, align the base with the shaft and tighten the mounting bolts evenly. Lubricate with lithium grease or an equivalent, following the manufacturer's recommended interval.
Pillow blocks with insert bearings from different brands often share standardized dimensions, but locking and sealing systems can differ. If you are replacing a SEALMASTER NPMH, compare the shaft diameter, the distance between holes and the center height. MR Industrial Accessories can suggest a compatible alternative or manufacture a custom solution if needed.

Frequently asked questions
- What does the NPMH code indicate on a pillow block with bearing?
- NPMH identifies a pillow block series with insert bearing. The following number indicates the shaft diameter, and the R suffix defines the insert's locking type. It is SEALMASTER's nomenclature for mounted units.
- How do I select the correct NPMH pillow block for my equipment?
- You need the shaft diameter, radial and axial loads, and environmental conditions. That data determines the sealing and lubrication. If you have the original bearing code, send it and we will indicate the equivalent option.
