DMX. The ultimate bearing material in
When you need a tough, durable, water-lubricated propulsion
bearing that can handle the rigors of harsh working environments
and result in near-zero shaft and sleeve wear, use DMX -
the revolutionary polymer alloy in a locking stave configuration.
It’s a unique, proprietary bearing material available only
from Duramax Marine.
BMT Defence Services Ltd. for the United Kingdom Ministry of Defence performed extensive tests in abrasive-laden waters reported these conclusions:
Can be used in a 2:1 or less L/D configuration.
This means less material, a smaller housing and less weight. Duramax DMX was tested successfully at 40 to 240 npsi. DMX Polymer Alloy Bearings are Class Approved by Lloyd’s for 2:1 L/D operation.
DMX operates with near-zero shaft/sleeve wear.
There was negligible shaft journal and bearing wear. In fact, the shaft finish in general improved on the vessel itself.
Grit has minimal effect on DMX.
No matter where you operate – from inland waters to open sea – DMX has proven
to effectively handle abrasive materials. It’s ideal for workboats, tugs, dredges
as well as ocean-going vessels.
Tests confirm DMX
performs better than Military Specification MIL-BDTL-17901C
Runs extremely well at low
shaft speeds without noise, vibration or stick slip.
It has an extremely low coefficient of friction at
breakaway and a full range of shaft speeds.
exceptionally well through multiple shaft reversals
with very little noise.
Allows engine to operate
with more efficiency and conserve fuel.
DMX Is Ideal
for Dredging Operations.
It’s the perfect material for
dredger bearings. DMX works great for propeller shafts
and withstands the rigors associated with cutting
