A SEALMASTER SPM pillow block is a mounted bearing unit that pairs a cast housing with an insert bearing. It bolts to your structure through two base holes and supports a rotating shaft. The insert can be swapped out on its own, so you do not have to replace the whole housing when the bearing wears. MR Industrial Accessories supplies this line to maintenance and purchasing teams across the United States and Latin America.

The SPM family uses a simple numeric code: SPM-19, SPM-23, SPM-27, SPM-28, SPM-31, SPM-35, SPM-39 and SPM-40. That number is not a shaft size or a load rating. It points to a specific housing size and its matching insert. To get the right unit, give us the full part number, or send the shaft diameter and base hole spacing, and we will identify the correct reference.

You will see these units on belt conveyors, bucket elevators, screens, mixers, mills, pumps and fans. Plants handling food, chemicals, grain and aggregates rely on them because mounting is straightforward and the insert seal keeps grease in while keeping dust out. They also show up in water treatment and packaging lines, where washdown and fast bearing changes matter.

Selection comes down to shaft diameter, radial and axial loads, and the operating environment. The insert seal tells you how much contamination the unit can handle; for dusty or wet conditions, choose a version with heavier protection. Mount on a flat base, tighten the bolts properly and align adjacent housings so the bearing does not carry extra load. Relubricate through the insert's grease fitting at intervals that match your service and temperature.

Insert-bearing pillow blocks from different brands can often be swapped if the mounting dimensions, shaft size and locking style line up. A competitor's part number may replace an SPM when the hole spacing and center height are the same. If you cannot find the original reference, MR Industrial Accessories will point you to a compatible alternative that avoids machine modifications.
