The SEALMASTER SF-C CR is a 4-bolt flange mounted bearing unit that supports rotating shafts on flat surfaces, keeping them centered and aligned. It is commonly used on conveyors, mixers, and other process equipment where combined loads and alignment matter. MR Industrial Accessories LLC supplies this line to customers across the United States and in several Latin American countries, and our team can help you confirm the correct variant for your shaft and operating conditions.

Reading the code helps you order the right replacement. In SF-C CR, the SF portion identifies the flange housing family, C refers to the mounting configuration, and CR indicates the sealing or built-in protection type. The number that follows, as in SF-20RC CR, tells you the shaft diameter the unit is sized for. With that nomenclature clear, you can request the exact part or ask about a size equivalent without confusion.

These flange housings are found in food processing, chemical, cement, and material handling operations, where a shaft needs four anchoring points on a flat surface. Typical equipment includes belt conveyors, bucket elevators, agitators, dryers, and continuous process lines. The 4-bolt flange simplifies mounting onto sheet metal or a steel structure, and it allows the shaft to be removed without taking apart the entire machine.

Selection comes down to a few key details: shaft diameter, the type of load (radial, axial, or combined), and the environment, whether that means humidity, dust, frequent washdowns, or extreme temperatures. The CR seal helps keep contaminants out and lubricant in. During installation, make sure the support surface is clean and flat, tighten the bolts in a cross pattern, and check shaft alignment to avoid parasitic stresses that can shorten bearing life.

Flange mounted bearings from different brands use their own nomenclatures, but mounting dimensions generally follow international standards. For a replacement, the practical approach is to compare the shaft diameter, the distance between holes, and the seal type. We can point you to a compatible alternative from the brands we supply, even if the original manufacturer's code does not match.

To get a quote, send the code from the housing or the equipment manual, such as SF-20RC CR, via WhatsApp or email. If the code is not visible, send a photo along with the main dimensions: shaft diameter, distance between hole centers, and fastening type. That lets us advise you accurately and avoid errors in the replacement.
