A recent survey by a global bearing
manufacturer concluded that around
25% of all rolling element bearings fail
prematurely due to ineffective and
inefficient seals. One design
consideration often overlooked by
end users and OEMs which can
negate a seal’s effectiveness and result
in early failure is shaft misalignment.

For peace of mind all of Revolvo’s
SRB split roller bearings are designed
to accommodate shaft misalignment
without reducing the effectiveness of
the seal. The SRB bearing’s design
locates both the bearing and the seal
within a separate swivelling housing,
which is then located within a
support pedestal. The external surface
of the housing and the internal
surface of the support pedestal are
spherical, creating a swivelling socket
joint which accepts up to ±3° of static
misalignment and ensures that seals
always remain concentric to the shaft.
