The SEALMASTER CRFBS-PN series is a 2-bolt flange mounted bearing that pairs an insert bearing with a flange housing. It mounts on flat surfaces to support rotating shafts in equipment that needs secure fastening and straightforward alignment, such as conveyors, fans, and mixers. The design simplifies installation and keeps maintenance points accessible.
The series code breaks down into useful blocks. CRFBS identifies the 2-bolt flange housing type, while PN marks a construction variant within the family. The number that follows, as in CRFBS-PN20R, tells you the shaft diameter the unit is built for. The trailing R denotes a specific version in the series. Reading the code this way helps you specify the right reference when you request a quote.
These housings suit food, chemical, textile, and material handling operations where shafts need solid, easy-to-install support. You will find them on packaging lines, agitators, dryers, and process equipment running in dusty or moderately humid conditions. The 2-bolt flange simplifies fastening to metal or sheet metal structures and allows removal of the assembly without fully dismantling the shaft.
Selection depends on shaft diameter, load type, and the operating environment. The insert bearing's sealing protects against contaminants; check that seal against your actual conditions. During mounting, keep the support surface clean and flat, and tighten the fastening screws evenly to prevent distortion. Correct lubrication and careful alignment support the service life of the assembly.
2-bolt flange mounted bearings can be interchanged across brands when the main dimensions match: shaft diameter, distance between flange holes, and overall height. Equivalent series from other manufacturers typically hold these dimensions, though sealing systems or housing materials may differ. Always confirm dimensional compatibility before replacing a component.
