The SPAW pillow block with insert bearing is a ready-to-install mounted unit that combines a cast housing with a ball insert bearing. It is used to support rotating shafts in equipment where base mounting is required, with alignment and lubrication already handled at the factory. MR Accesorios Industriales sells this NTN line in Buenos Aires, Argentina, with more than 80 years of experience in power transmission components.
The SPAW series designation reads as a code that identifies the type of housing and the insert bearing it carries. For example, SPAW2211-115N1 indicates a pillow block with an insert bearing of the 2211 series and a shaft diameter of 115 (in some nomenclatures, the numeric suffix refers to the measurement in inches or millimeters). In SPAW2211N1, however, the size suffix does not appear, suggesting a variant with a standard metric shaft. Codes such as SPAW2213-203N1 or SPAW2215-207N1 show how the bearing size and shaft measurement change depending on the application. The N1 suffix usually indicates a design feature specific to the series.
These pillow blocks are used in a wide variety of industries in Argentina: from food plants and cold storage facilities to textile factories, cement plants and water treatment plants. They are common in belt conveyors, bucket elevators, mixers, fans and centrifugal pumps. Their pillow block design allows them to be mounted on metal structures or concrete bases, making assembly and maintenance easier. Being self-aligning units, they tolerate small misalignments between the shaft and the housing, which extends the service life of the assembly.
To select the right pillow block, take into account the shaft diameter, the radial and axial load it must support, and the environmental conditions. The sealing of the insert bearing is key: in dusty or humid environments, it is advisable to choose versions with higher protection seals. Factory lubrication is usually sufficient for most applications, but at high temperatures or speeds it is recommended to follow the manufacturer's instructions. Assembly must ensure correct alignment between the pillow blocks and the shaft, and the base fastening must be firm to prevent vibrations.
As for equivalents, NTN SPAW pillow blocks can be interchanged with units from other manufacturers that follow the same mounting standard and dimensions. It is important to verify the shaft diameter, the distance between base holes and the center height, since these parameters define compatibility. If you are replacing an existing unit, compare the critical dimensions and the type of sealing. MR Accesorios Industriales can advise you to find the equivalent unit that best suits your equipment.
