The NPL pillow block with SEALMASTER insert bearing is a mounted pillow block bearing, designed to support rotating shafts in industrial equipment. It consists of a cast iron housing and an insert bearing with an extended inner ring, which is locked to the shaft with set screws. Its mounting simplifies installation and maintenance in conveyors, fans, mixers and other machines that require robust fastening and constant alignment.

The NPL designation identifies the series of pillow blocks with insert bearing. In the examples NPL-20R and NPL-32R, the number that follows the letters indicates the shaft diameter in millimeters: 20 and 32 mm respectively. The R suffix distinguishes the insert configuration, which in this series includes an extended inner ring with set screws for shaft locking. Knowing this nomenclature allows you to select the right pillow block according to your equipment's shaft size.

These pillow blocks are used in a wide variety of industrial applications in Argentina: conveyor belts, bucket elevators, mills, mixers, fans, pumps and equipment for the food, chemical, cement and aggregate industries. Their pillow block design allows them to be mounted on steel structures or concrete bases, making alignment and replacement of the insert bearing easier without completely disassembling the shaft.

To select the correct NPL pillow block, take into account the shaft diameter, radial and axial loads, and environmental conditions. Check that the housing sits well supported and aligned; misaligned mounting accelerates wear. Lubrication of the insert is essential: follow the manufacturer's recommendations and periodically check the condition of the seals to prevent contaminant entry. The set screws must be tightened with the proper wrench to ensure locking.
