Split plummer block housings SE 2, 3, 5 and 6 series

Features and benefits Fig. 2
SE plummer block housings in the 2, 3, 5 and 6 Reinforcement rib in the base
series have the following features and benefits:
Stiffer and more robust housing
The 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
(† figs. 2 and 3), 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 dissipation
The ribs around the perimeter and in the
centre of the base († fig. 3) are larger, to
increase the contact area between the base Fig. 3
and support surface. This results in improved Enlarged central rib for better support and heat
heat flow from the bearing outer ring to the dissipation
support surface.
Improved markings on the housing
The 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. 4).
The designation on the housing cap has also
been enhanced for readability and now con-
tains the complete housing designation, i.e.
with variant suffixes, for better traceability
(† fig. 5).
