The SEALMASTER SF series Y-bearing with insert is a 4-bolt flange mounted bearing. It is used to support rotating shafts on structures where the flange is bolted to a flat face, with the shaft passing through perpendicular to that surface. It is a compact, easy-to-mount solution for equipment that needs a self-aligning, sealed unit, available in Buenos Aires, Argentina, through MR Accesorios Industriales.

The SF series designation reads as a size code: the number following the letters indicates the nominal shaft size, and the final letter R distinguishes this 4-bolt flange variant. For example, SF-20R and SF-32R correspond to two sizes in the same family. The R suffix does not change the mounting type, but it does identify the flange configuration within the SF series.

These housings appear in conveyors, belts, elevators, mixers, fans and process lines in food, chemical, cement and aggregate processing plants. In Argentina they are found in materials handling equipment and in machines where a robust, easily replaceable flange unit is needed. The 4-bolt flange allows it to be fastened to sheet metal or structure with simple alignment.

To select the housing, take into account the shaft diameter, the type of load (radial, axial or combined) and the environmental conditions. The insert's sealing defines the protection against dust, water or frequent washdowns. During mounting, verify that the flange seats without deformation, that the bolts are tightened evenly and that the shaft is aligned. Proper lubrication and the insert's internal clearance influence service life.

Flange mounted bearings are available from different brands with their own nomenclatures. Interchangeability depends on the flange dimensions, the shaft diameter and the insert's locking type. A similar code is not enough: you have to compare the hole spacing, the flange diameter and the overall height. If you need to replace an existing unit, send us the original code and we will indicate the compatible alternative.

If your equipment uses an SF series 4-bolt flange housing, write to us on WhatsApp with the code on the nameplate. At MR Accesorios Industriales we will quote the SEALMASTER reference and help you define the right option for your application. We can also evaluate variants in the same family if the mounting requires it.
