ROMOR I Dovetail Stave Bearings
All-polymer dovetail stave bearings for commercial and naval stern tubes, with friction coefficient under 0.001, low stick-slip at slow speeds and grit rejection; used on most U.S. Navy surface ships and submarines.
Description
ROMOR I dovetailed staves are all-polymer water-lubricated bearing staves for naval bronze housings in commercial marine and naval stern tubes, designed for low friction and noise even at minimal journal velocities. They combine a glass-smooth facing with an ultra-high molecular weight polymer alloy backing.
Key features
- Hydrodynamic design minimises bearing and journal wear; coefficient of friction under 0.001
- Low friction at slow shaft speeds reduces stick-slip
- "Elastic hydrodynamic" grit rejection; durable in gritty, dirty water
- 1/4 the weight of brass-backed staves; replaceable without removing the bearing from the vessel
- Corrosion resistant, easily removed from segmental housings
Configurations
Available in two configurations, including radius-backed for standard cylindrical stern tubes.
Applications
Fitted on 90% of surface ships and submarines in the U.S. Navy fleet and on many other navies' vessels.
