The SEALMASTER RPB-CR is a four-bolt flange mounted bearing that fastens a rotating shaft to a flat surface with a rigid, centered hold. It fits where the shaft runs on a vertical or horizontal plane and a pillow block will not fit. MR Industrial Accessories supplies this SEALMASTER line with options for the shaft sizes you work with.
Reading the code helps you order correctly. RPB marks the four-bolt flange family. The number after it — 204, 207, 211, 300, 303 — gives the shaft size the unit is built for. C4 covers the housing configuration and how the inner bearing is fastened. CR sets the sealing and lubrication variant. So an RPB 204-C4 CR and an RPB 300-C4 CR share the same format but differ in shaft diameter and load capacity.
You will find these units on conveyor lines, mixers, fans, pumps, belts and process equipment where the shaft mounts to a plate or profile structure. The four-bolt flange lets you align and tension the drive without machining an extra seat, which helps when replacing a mounted bearing in place.
Selection comes down to shaft diameter and load type: radial, axial or combined. The CR seal guards against dust and moisture, but for pressure washing or abrasive material, consider adding extra protection. At mounting, set the flange on a clean, flat surface, tighten the four bolts in a cross pattern, and confirm the shaft turns without axial play. Factory lubrication is normally enough for start-up; in continuous duty, grease according to the duty cycle.
Mounted units interchange between brands by shaft number and flange configuration, not by the full part number. If your equipment runs a SEALMASTER RPB-CR, an equivalent with the same shaft size and similar capacity may work, but compare hole diameter, center distance and sealing type. Send the old part number and we will point you to a compatible alternative.

Frequently asked questions
- What does RPB-CR mean in a SEALMASTER unit?
- RPB is the four-bolt flange family. The number after it indicates shaft size. C4 is the housing configuration, and CR is the sealing and lubrication variant. The complete part number defines the assembly.
- How do I choose a replacement for a mounted unit?
- Check shaft diameter, flange hole spacing, sealing type and load capacity. A matching shaft number alone is not enough; the flange and sealing must also suit your equipment.
- What lubrication does an RPB-CR unit take?
- These units arrive lubricated from the factory. In continuous service, grease according to the duty cycle and environment. With dust or moisture present, inspect the sealing before relubricating.
