FNL flanged housings are non-split housings that are produced in two designs depending on size. Smaller sizes up to and including size 13 have a triangular flange (fig. 1), larger sizes have a square flange (fig. 2).
FNL housings are supplied with a cover either for shaft ends (fig. 3) or for through shafts (fig. 4). The housings with a cover for shaft ends have the designation suffix A, the housings with a cover for through shafts have the designation suffix B.
