Description

SEALMASTER SF-20R is a flange bearing 4 holes reference, within Bearing housings. Request a quote for SF-20R via WhatsApp or email with the quantity you need; we respond promptly with lead time and equivalents.

The SEALMASTER SF series Y-bearing housing 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 perpendicular to that surface. It is a compact and easy-to-mount solution for equipment requiring a self-aligning and sealed unit, available in Buenos Aires, Argentina, through MR Accesorios Industriales.

The SF series designation is read 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 of 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 material handling equipment and in machines where a robust and easily replaceable flanged unit is needed. The 4-bolt flange allows fixing it to sheet metal or structure with simple alignment.

To select the housing, consider the shaft diameter, the type of load (radial, axial or combined) and the environmental conditions. The insert seal 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. Adequate lubrication and the internal clearance of the insert influence service life.

Flanged mounted bearings are available from different brands with their own nomenclatures. Interchangeability depends on the flange dimensions, shaft diameter and insert locking type. It is not enough for the code to be similar: you must compare the distance between holes, the flange diameter and the overall height. If you need to replace existing equipment, 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 via WhatsApp with the code SF-20R, SF-32R or the one shown 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 of the same family if the mounting requires it.

Frequently Asked Questions

What does the SF series mean in a Y-bearing housing with insert?
The SF series identifies a 4-bolt flange mounted bearing. The number following the letters indicates the nominal shaft size, and the R suffix distinguishes the flange configuration. For example, SF-20R and SF-32R are two sizes of the same family.
How do I choose the right housing for my shaft?
You need the shaft diameter, the type of load and the working conditions. The sealing and lubrication of the insert also matter. If you send us the original equipment code, we will indicate the equivalent SEALMASTER reference for a quote.
Can I replace a housing from another brand with a SEALMASTER one?
Yes, as long as the flange dimensions, the distance between holes and the shaft diameter match. Interchangeability does not depend only on the code. Write to us via WhatsApp with the model and we will confirm the compatible alternative.
