  We consider a class of left-right symmetric model with enlarged gauge group
$SU(3)_c \times SU(3)_L \times SU(3)_R \times U(1)_X$ without having scalar
bitriplet. In the absence of scalar bitriplet, there is no Dirac mass term for
fermions including usual quarks and leptons. We introduce new isosinglet
vector-like fermions so that all the fermions get their masses through a
universal seesaw mechanism. We extend our discussion to neutrino mass and its
implications in neutrinoless double beta decay ($0\nu\beta\beta$). We show that
for TeV scale $SU(3)_R$ gauge bosons, the heavy-light neutrino mixing
contributes dominantly to $0\nu\beta\beta$ that can be observed at ongoing
experiments. Towards the end we also comment on different possible symmetry
breaking patterns of this enlarged gauge symmetry to that of the standard
model.
