The SEALMASTER RPB-CR unit is a four-bolt flange mounted bearing, designed to secure rotating shafts to flat structures with rigid, centered fastening. It is used when the shaft needs support on a vertical or horizontal plane and there is no room for a pillow block. MR Accesorios Industriales carries this SEALMASTER line, a brand that MR carries, with alternatives for every shaft size.

The RPB-CR designation reads in parts: RPB identifies the family of four-bolt flange units; the number that follows —204, 207, 211, 300, 303— indicates the shaft size for which the assembly is made; C4 indicates the housing configuration and the fastening type of the inner bearing; and CR distinguishes the sealing and lubrication variant. Thus, an RPB 204-C4 CR and an RPB 300-C4 CR share the format but differ in shaft diameter and load capacity.

These units appear in conveyor lines, mixers, fans, pumps, belts and process equipment where the shaft is mounted on a plate or a profile structure. In Argentina they are seen in food plants, cement plants, tanneries and in the field, on seeders and harvesters. The four-bolt flange allows aligning and tensioning the drive without machining an additional seat, which is useful when replacing a mounted bearing on site.

To choose well, look at the shaft diameter and the load type: radial, axial or combined. The CR sealing protects against dust and moisture, but if there is pressure washing or abrasive material, an extra protection should be evaluated. During mounting, rest the flange on a clean, flat surface, tighten the four bolts in a cross pattern and check that the shaft turns without axial play. Factory lubrication is usually enough for start-up, but in continuous service it is worth greasing according to the duty cycle.

Mounted units are interchanged between brands by shaft number and flange configuration, not by complete part number. If the equipment carries a SEALMASTER RPB-CR, an equivalent from another firm with the same shaft size and similar capacity may work, but the hole diameter, center distance and sealing type must be compared. MR Accesorios Industriales indicates the compatible alternative when you send the old part number.

If you need to replace a flange unit, send the complete part number on WhatsApp —for example RPB 208-C4 CR— and we'll quote it promptly. We can also verify the shaft size and suggest the variant that best suits your application.
