A foot-mounted assembly that pairs a cast iron housing with a ball insert bearing, the SEALMASTER SPD pillow block arrives ready to bolt onto a bedplate. It suits shaft support in transmission and conveying machinery where space is tight, some misalignment is expected, and installation should stay simple. MR Industrial Accessories supplies this SEALMASTER series, which covers the shaft sizes commonly requested by US and Latin American plants. Selection starts with the shaft diameter and the mounting style you need.

Read the series code as a size reference rather than a measurement. The letters name the family; the trailing number points to the shaft size the unit is built for. In SPD-14, SPD-15, SPD-16, SPD-19, SPD-20, SPD-22, SPD-23 and SPD-24, only that last figure changes, tracking the shaft diameter. Treat it as an internal series reference tied to a standardized shaft size, not a millimeter value. Send the full part number, or simply the shaft diameter, and we will quote the matching unit.

Typical installations include belt conveyors, bucket elevators, mixers, screens, mills and packaging lines, plus water treatment, food and beverage, and chemical plants where foot mounting keeps the unit accessible for cleaning. In agriculture they turn up on seeders, combine harvesters and grain handling equipment. They fit situations where the shaft turns at moderate speed and a sturdy cast iron housing is wanted to handle dust, moisture and combined radial loads.

When selecting, weigh the shaft diameter, the radial and axial load, and the working environment. Self-alignment in the SPD series absorbs small shaft-to-bedplate misalignments. The insert seal keeps dust and moisture out; where washdown or heavy contamination is routine, review which seal type is appropriate. At mounting, check that the base sits flat, tighten the bolts, and lubricate to suit the duty cycle. Good alignment pays off in bearing life.

Insert bearing pillow blocks from various brands frequently interchange when shaft diameter, center height and mounting hole spacing line up. For a quote, send the original part number plus the key dimensions, or just the shaft diameter and the hole spacing. MR Industrial Accessories supplies SEALMASTER and can point you to a compatible option in the same series or another equivalent line. Having the data sheet on hand is not necessary; the part number identifies the unit.

For an SPD pillow block on equipment already running, send the part number or shaft diameter through WhatsApp or email. We will quote the unit and, where the assembly calls for it, suggest a compatible alternative. We can also advise on mounting and lubrication so the assembly runs aligned and free of vibration.
