The SEALMASTER RFP series is a piloted flange mounted bearing unit designed to bolt directly onto a machined face. The pilot shoulder centers the assembly in the bore, so no separate seat has to be machined. This makes it a practical choice for transmission, conveying and process equipment where a compact unit that is easy to replace is preferred. MR Industrial Accessories LLC supplies this line.

Reading the designation is straightforward. The figure after RFP gives the bore in millimeters, and the MM suffix confirms metric measurement rather than inches. A 35 mm shaft therefore calls for RFP-35MM, a 40 mm shaft for RFP-40MM, and the same logic applies upward. The series runs continuously through RFP-45MM, RFP-50MM, RFP-55MM, RFP-60MM, RFP-65MM and RFP-70MM, covering a range of metric shaft diameters.

Typical installations include belt conveyors, bucket elevators, mixers, mills, centrifugal pumps and other process equipment in food, chemical and aggregate plants. The piloted flange simplifies mounting on sheet metal or cast iron and handles combined loads. These units also turn up on road machinery and material handling equipment working in dusty or damp conditions.

Selection starts with matching the shaft diameter to the number in the designation and confirming that the flange pilot fits the bore. Sealing deserves attention as well: SEALMASTER housings generally use lip seals to keep contaminants out, and in very dirty environments extra protection is worth considering. When mounting, seat the flange against the face and tighten the bolts in a cross pattern so the housing does not distort. Relubricate according to the manufacturer's recommendation and adjust the interval to the service conditions.

Piloted flange housings are sold under several brand nomenclatures. For a replacement, the part number alone is not enough: compare bore diameter, flange type, bolt hole center distance and sealing arrangement. A unit from another brand with the same shaft size and a similar flange layout can often be interchanged, but confirm the critical dimensions before installing. If anything is unclear, send the measurements or the drawing and we will point you to a compatible option.

To request a SEALMASTER RFP series housing, message us on WhatsApp or by email with the full part number, for example RFP-45MM, or with your shaft and flange measurements. We reply promptly and help you confirm the right reference. If you need a variant with a different seal or fixing arrangement, we can also suggest alternatives.
