Split plummer block housings SNL 30, 31 and 32 series

             Features and benefits                                            Fig. 2
             SNL plummer block housings in the 30, 31 and   Reinforcement rib in the base
             32 series have the following features and
             benefits:

             Stiff housing
             The housing base is reinforced with ribs and
             has extra material surrounding the holes for
             the attachment bolts († fig. 2). This virtually
             eliminates any distortion of the base and bear-
             ing seat during tightening of the attachment
             bolts.
             Good heat dissipation
             The centre cross reinforcement in the housing
             base († fig. 3) increases the contact area
             between the housing base and the support
             surface to improve the heat flow from the
             bearing outer ring to the support surface.                       Fig. 3
                                                  Centre cross for better heat conduction
             Caps and bases individually marked
             The housing cap and base are matched during
             manufacture and are not interchangeable with
             the caps and bases of other housings. To pre-
             vent any mismatches, a unique serial number
             is marked on both the housing cap and the
             base († fig. 4).
             Dimples to locate accessories
             Dimples cast into the housing cap indicate
             where grease fittings and condition monitor-
             ing sensors can be mounted for maximum
             effectiveness († fig. 5).
             Simple mounting
             To simplify mounting and make alignment
             more accurate, lines indicating the centre of                    Fig. 4
             the bearing seat and housing bore axis are   Individually marked cap and base
             cast into the housing base. Dimples indicate
             the position for dowel pins († fig. 6). Mount-
             ing instructions are supplied with each seal
             pack. The housings have two eyebolts on the
             cap for safe and easy handling.
