The SEALMASTER RCI-M series is a spherical roller insert bearing with an extended inner ring, made to sit in split plummer block housings and housing units. It suits shafts that are locked with set screws and assemblies where some misalignment is acceptable. MR Industrial Accessories supplies this line and helps you match the right part number to your application.
Reading the code: RCI marks the insert bearing family with an extended inner ring, M stands for the metric series, and the figure after the hyphen is the shaft size in millimeters. So RCI-35MM fits a 35 mm shaft, RCI-40MM a 40 mm shaft, and RCI-50MM a 50 mm shaft. Include the full part number when you request a quote so we can confirm the exact insert.
Typical installations include conveyors, belt systems, elevators, mills, mixers and process equipment, as well as industrial fans and large centrifugal pumps. These are moderate-speed applications where small misalignments need to be absorbed. Plants in food processing, cement, mining and paper production are common users of this series.
When choosing the insert, look at shaft diameter, load type and operating environment. Sealing matters: in dusty or wet conditions, pick the version with a reinforced seal. Make sure the housing accepts the RCI-M series and that the set screws in the inner ring are compatible with the shaft hardness. Use the lubricant specified for spherical roller bearings, and align the housings during mounting.
For interchangeability, insert bearings from different brands can replace one another only if the main dimensions, locking method and sealing match. A matching shaft diameter alone is not enough: check inner ring width, set screw thread and housing geometry. If your equipment uses another brand, send us the part number and we will point you to a compatible SEALMASTER option or another brand we carry.

- How can I tell if this insert will replace the one in my equipment?
- Check the shaft diameter, inner ring width, locking type and sealing. Send us the original bearing part number via WhatsApp and we will indicate the equivalent in the RCI-M series or another compatible alternative.
- What should I consider for mounting?
- Confirm the housing is compatible, the shaft is in good condition and the set screws tighten correctly. Use a lubricant suitable for spherical roller bearings and align the housings before securing the insert.
