Description
SEALMASTER RFPA-45MM belongs to piloted flange bearing, part of our Bearing housings range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for RFPA-45MM and any equivalents.
SEALMASTER RFPA series piloted flange housings arrive as a complete assembly: bearing, housing and sealing system in one unit. The pilot shoulder centers the housing in a machined bore, which helps with alignment and speeds up installation. These units suit applications where the flange bolts to a face and the shaft runs perpendicular to it.
The RFPA code covers SEALMASTER's piloted flange housing family. The number after the dash gives the nominal shaft size in millimeters, and the MM suffix confirms metric sizing rather than inches. The series runs from RFPA-45MM through RFPA-80MM, with RFPA-50MM, RFPA-55MM, RFPA-60MM, RFPA-65MM, RFPA-70MM and RFPA-75MM in between. To pick a size, identify the shaft diameter and the flange mounting type.
You will find these housings on conveyors, elevators, mixers, pumps, fans and process lines where the bearing needs to sit on a circular flange. The piloted design mounts to sheet metal or cast iron with a machined bore and handles moderate radial and axial loads. When selecting, check shaft diameter, pilot diameter and depth, and the distance between flange holes. Sealing matters: in wet or dusty areas, extra protection is worthwhile. Use the lubricant specified for the speed and operating temperature, clean the pilot before mounting, and tighten bolts in a cross pattern to avoid distorting the housing. Good alignment supports bearing life.
SEALMASTER is a Regal Rexnord brand, and its mounted housings often interchange with other brands that use standardized metric sizes. Interchange depends on shaft diameter, flange type and pilot dimensions, not on the commercial part number. For a replacement, send the part number stamped on the housing or the main dimensions, and we will point you to a compatible option.
MR Industrial Accessories LLC supplies the SEALMASTER line to customers across the United States and in several Latin American countries. If you need an RFPA housing, send the part number or the shaft and pilot dimensions by WhatsApp or email. Our team replies promptly, suggests equivalents and helps you choose the right unit for your application.

Frequently asked questions
- How do I determine the size of an RFPA housing?
- The number in the designation is the nominal shaft diameter in millimeters. RFPA-45MM, for instance, fits a 45 mm shaft. Confirm by measuring the shaft with a caliper and checking the pilot diameter and flange hole spacing.
- What sets a piloted flange housing apart from a flat flange housing?
- The pilot is a machined shoulder that centers the unit in the equipment's bore, which simplifies alignment and prevents shifting. A flat flange sits directly on the surface and needs external centering.
- Can a SEALMASTER RFPA replace a housing from another brand?
- Yes, if the shaft diameter, flange type and pilot dimensions match. Interchangeability follows standardized dimensions rather than the part number. Send the dimensions or the original part number by WhatsApp or email and we will confirm the equivalent.
