SEALMASTER SF-31C CR is a flange bearing 4 holes reference, within Bearing housings. Request a quote for SF-31C CR via WhatsApp or email with the quantity you need; we respond promptly with lead time and equivalents.
The SEALMASTER SF-C CR flange unit is a 4-bolt flange mounted bearing, designed to secure rotating shafts to a flat surface with a compact and easy-to-align arrangement. It is used in equipment where the bearing must be flanged to the frame, with the flange as the only anchoring point. MR Accesorios Industriales sells this line as a brand, with more than 80 years of experience in the Argentine industrial market.
The SF-C CR series designation is read in parts: SF identifies the flange unit family, C the construction variant and CR the sealing type. The number between SF and C —as in SF-12C CR, SF-16C CR or SF-20C CR— indicates the size of the mounted bearing, not a measurement in millimeters. Each part number combines those letters and that number to define the flange and the inner bearing. At MR we quote by full part number.
These units are used in conveyors, mixers, blowers, centrifugal pumps, packaging lines and process equipment in general. In Argentine industry they appear in food, chemical, cement and aggregate processing plants, where the 4-bolt flange allows mounting the bearing onto sheet metal or a structure without machining a housing. They are also used in agricultural machinery and in material handling equipment operating with horizontal or inclined shafts.
To select the unit, consider the shaft diameter, the type of load —radial, axial or combined— and the environmental conditions. The CR seal protects against dust and moisture, so it is suitable for dirty environments or frequent washdowns. Check the alignment of the flange with the shaft line: a poorly seated flange creates stress on the bearing and shortens its service life. Lubrication must be the one specified for the mounted bearing and renewed according to the duty cycle.
SEALMASTER SF-C CR units are interchangeable with other brands of 4-bolt flange mounted bearings that share the same hole pattern and shaft diameter. To choose an equivalent, compare the full part number, the number of holes and the sealing type. If you need to replace an existing unit, send us the part number stamped on the part and we will indicate the compatible alternative within the line we sell.
If you are looking for a flange unit for your equipment, send the part number —for example SF-23C CR or SF-31C CR— via WhatsApp to MR Accesorios Industriales. We will quote it shortly and, if you need a variant that does not appear in the list, write to us with the model your machine requires. We also advise on mounting and lubrication so that the unit works under the correct conditions.
