The SEALMASTER RCI-M series is a spherical roller insert bearing with an extended inner ring, built for installation in split plummer block housings and other split housings. It suits shafts that need support while allowing a small amount of misalignment, and it can be fitted or removed with the equipment still in place. MR Industrial Accessories supplies this line to industrial customers in the United States and Latin America.

Reading the code helps you match the part quickly. RCI marks the insert bearing family made for split housings, M identifies this series, and the figure that follows gives the shaft size the inner ring bore fits, as seen in RCI35MM-N, RCI40MM-N and RCI50MM-N. The -N ending points to a construction variant inside the same series. Examples in the series run from RCI35MM-N through RCI70MM-N, and the naming logic stays the same across the range.

These inserts are common on equipment that runs continuously: conveyor belts, bucket elevators, mills, mixers, high-flow centrifugal pumps, industrial fans, and machinery in cement, mining, food and aggregate processing. The split housing design lets maintenance crews work on the shaft without pulling the whole assembly apart, which matters on lines where downtime is costly. Pairing spherical rollers with a split housing keeps service work simpler.

Selection comes down to a few points: shaft diameter, whether the load is radial, axial or combined, and the conditions around the bearing. The seal determines how well the insert handles contamination, so dusty or wet locations call for tighter protection. Use the lubricant specified for the operating speed and temperature, and make sure the housing sits well supported and aligned with the shaft. Correct internal clearance and a proper fit on the inner ring are what keep premature failures away.

This series can be swapped with equivalent references from other brands when shaft dimensions, outer diameter and inner ring width line up. A matching part number alone is not enough; dimensions, shaft fixing method and sealing have to be checked. If your original equipment uses a SEALMASTER insert, staying with the same designation is the simplest route. Otherwise, compare the geometry and settle on the compatible option. MR Industrial Accessories can point you to the right choice.
