SEALMASTER CRFCF-PN20R is a reference of piloted flange bearing, within Bearing housings. Request a quote for CRFCF-PN20R via WhatsApp or email with the quantity you need; we respond promptly with the quote and equivalents.

The SEALMASTER CRFCF-PN series unit is a piloted flange mounted bearing: the unit combines the cast housing with the bearing already inserted and locked, so it mounts as a single piece onto the machine face. It is used when a rotating shaft must be supported against a flat surface and the housing cannot be slid on from the side, which is common in process, conveying and material handling equipment.

The series designation is read in blocks. The initial letters identify the housing type and its flange configuration, and the suffix PN defines the unit variant within that family. The number appearing before the final R is the size code: that is why CRFCF-PN20R and CRFCF-PN32R are two different sizes of the same series. By sending the complete part number on WhatsApp, MR Accesorios Industriales will quote you the unit that corresponds to your shaft.

These units appear in belt and chain conveyors, elevators, mixers, blowers, pumps and process equipment where the shaft is supported on a flange bolted to a panel or structure. In food, chemical, aggregate and water treatment plants they are chosen precisely because mounting is frontal and the unit remains accessible for inspection and relubrication without disassembling the entire equipment.

To select the unit, start from the shaft diameter you need and the flange hole pattern: the piloted design centers the unit in the machined housing, so the fit between pilot and housing defines alignment. Also check the sealing according to the environment (dust, water, washdown), the lubricant type and the possibility of relubrication. During mounting, tighten the flange in a cross pattern and verify that the shaft turns freely before starting the machine.

Equivalent units from different brands with their own nomenclature coexist in the market: two similar-looking part numbers may differ in locking system, sealing or housing tolerances. Interchangeability is confirmed by comparing shaft dimensions, pilot, flange pattern and insert type, not just the part number. If you send us the original part number or a photo of the nameplate, we will indicate the compatible alternative from the CRFCF-PN series.

If the equipment is down, send the part number on the old unit, the shaft dimension or the machine model by WhatsApp. With that we will quote you the SEALMASTER unit from the CRFCF-PN series that corresponds and, if you need another flange or sealing configuration, we will indicate the alternative within the mounted bearing line. The response is prompt.
