             SKF provides an assortment of housings for
             paper machines. The four standard housing
             series that are covered in this publication
             include:
             •  SBFN series, for felt rolls
             •  SBPN series, for drying cylinders
             •  SDM series, for Yankee cylinders
             •  SNL … TURP series, for drying cylinders and
               felt rolls
             SBFN felt roll housings († fig. 1) are non-
             split housings. They consist of a housing body
             and two covers with integrated seals. The base
             has two oblong cast holes for attachment bolts.
             Oblong attachment bolt holes enable exact
             positioning of the housing during mounting to                    Fig. 2
             fully exploit the potential of CARB toroidal roller   SBPN drying cylinder housings
             bearings to accommodate thermal elongation
             of the shaft. For dimensions and detailed
             specifications of SBFN housings, contact SKF.
               SBPN drying cylinder housings († fig. 2)
             are non-split housings. They consist of a hous-
             ing body and two covers with integrated seals.
             The base has four cast holes for attachment
             bolts. Housings for spherical roller bearings
             have open-ended attachment bolt holes.
             Housings for CARB toroidal roller bearings
             have oblong attachment bolt holes. They
               enable exact positioning of the housing during
             mounting to fully exploit the potential of CARB
             toroidal roller bearings to accommodate ther-
             mal elongation of the shaft.
               SDM Yankee cylinder housings († fig. 3)
             are split housings consisting of a cap, base and                 Fig. 3
             two covers with integrated seals. The inboard   SDM yankee cylinder housings
             cover is split to enable removal of the cover
             without removing the cap. To facilitate hand-
             ling, the cap has two integral flanges, with a
             hole cast into each one. The base has four
             holes for attachment bolts. Housings for
             spherical roller bearings have drilled attach-
             ment bolt holes. Housings for CARB toroidal
             roller bearings have oblong attachment bolt
             holes. They enable exact positioning of the
             housing during mounting to fully exploit the
             potential of CARB toroidal roller bearings to
             accommodate thermal elongation of the shaft.
