A mounted unit built around a cast iron housing and a SEALMASTER insert bearing, the NPL pillow block carries rotating shafts on conveyors, fans, mixers and similar machinery. The insert uses an extended inner ring held on the shaft by set screws, so the unit bolts down easily and keeps the shaft aligned over time.
Reading the code helps you order the right size. NPL names the pillow block series with insert bearing; the digits that follow give the shaft bore in millimeters, so NPL-20R takes a 20 mm shaft and NPL-32R a 32 mm shaft. The R ending points to the insert configuration used in this series, an extended inner ring locked with set screws. Match that bore to your shaft before you order.
Because the housing is a separate piece from the insert, the unit can be bolted to steel frames or concrete pads and the bearing cartridge swapped out without pulling the whole shaft. That layout suits conveyors, bucket elevators, mills, mixers, fans, pumps, and equipment in food, chemical, cement and aggregate plants.
Sizing comes down to shaft diameter, the radial and axial loads the application imposes, and where the unit will sit. Set the housing on a flat, well supported surface and check alignment, since a unit mounted out of line wears faster. Keep the insert lubricated on the schedule the manufacturer gives, inspect seals regularly so contaminants stay out, and tighten the set screws with the correct wrench.
SEALMASTER insert bearing pillow blocks can be swapped with other brands built to the same mounting standard and dimensions. Have the full part number ready, for example NPL-20R, along with the working conditions, and our team can point you to a compatible option. MR Industrial Accessories LLC supplies SEALMASTER and serves customers throughout the United States and in several Latin American countries.
