A SPAW pillow block with an NTN insert bearing arrives as a complete mounted unit: a cast housing paired with a ball insert bearing, aligned and lubricated before it leaves the factory. It supports rotating shafts on equipment that mounts to a base, so installation is mostly a matter of bolting down and tightening. MR Industrial Accessories LLC supplies this NTN line to customers throughout the United States and in several Latin American countries.

Reading the SPAW code helps you order the right unit. In SPAW2211-115N1, the 2211 points to the insert bearing series and 115 to the shaft size, which in some nomenclatures is given in inches or millimeters. SPAW2211N1 carries no size suffix, which points to a variant with a standard metric shaft. Other references, such as SPAW2213-203N1 and SPAW2215-207N1, show how the bearing size and shaft measurement shift from one application to the next. The N1 ending generally marks a design feature specific to the series.

You will find these units in food plants and cold storage rooms, textile factories, cement plants and water treatment facilities. Typical equipment includes belt conveyors, bucket elevators, mixers, fans and centrifugal pumps. Because the housing mounts to metal structures or concrete bases, assembly and maintenance stay straightforward. The self-aligning design also absorbs small misalignments between shaft and housing, which helps the assembly last.

Selection comes down to three things: shaft diameter, the radial and axial load the unit must carry, and the conditions on site. Sealing deserves close attention, since dusty or humid areas call for insert bearings with higher protection seals. Factory lubrication covers most applications, though high temperatures or speeds mean you should follow the manufacturer's instructions. When mounting, keep the pillow blocks and the shaft properly aligned and fasten the base firmly to avoid vibration.

For replacements, SPAW pillow blocks can be interchanged with units from other manufacturers that share the same mounting standard and dimensions. Check the shaft diameter, the distance between base holes and the center height, as these define compatibility. When swapping out an existing unit, compare the critical dimensions and the seal type.
