Features and benefits
SE plummer block housings in the 2, 3, 5 and 6 series have the following features and benefits:
Stiffer and more robust housingThe new, optimized design together with their stronger material grade make SE housings more robust compared to SNL housings.
With larger ribs in the base, and additional material around the holes for attachment bolts (fig. 1 and fig. 2), SE housings are stiffer than their predecessors. The attachment bolts can be preloaded to locate the housing without deforming the base or housing bore.
Better heat dissipationThe ribs around the perimeter and in the centre of the base (fig. 2) are larger, to increase the contact area between the base and support surface. This results in improved heat flow from the bearing outer ring to the support surface.
Improved markings on the housingThe housing cap and base are matched during manufacture and are not interchangeable with the caps and bases of other housings. A unique serial number on both housing parts helps avoid any mismatches (fig. 3).
The designation on the housing cap has also been enhanced for readability and now contains the complete housing designation, i.e. with variant suffixes, for better traceability (fig. 4).
Dimples to locate accessoriesDimples cast into the housing cap indicate where grease fittings and condition monitoring sensors can be mounted for best results (fig. 5).
Simpler mountingThe grease fitting kit contains torque values for the cap bolts and data for initial grease fills.
To simplify mounting and make alignment more accurate, lines indicating the centre of the bearing seat and housing bore axis are cast into the housing base. Dimples indicate the position for dowel pins (fig. 6). Mounting instructions are supplied with each seal pack.
