Rudder Port Bearing - Type D without Fiberglass Liner - 2-1/4" Rubber Stock

The Tides Marine Type-D rudder port is an integrated approach to rudder port installation. It is for boats constructed of FRP. It can be used for new boat construction and is also easy to use as a retrofit for replacing other types of conventional rudder ports. No tooling is required.
The Type-D is a sealed bearing consisting of a UHMW housing with a nitrile rubber lip seal. It eliminates metal-to-metal abrasion and electrolytic corrosion.
The Tides Marine Type D system components include the Type D bearing and seal but NOT the FRP liner, see related products for the kit with liner.
The Type D rudder bearing and seal assembly consists of a one-piece UHMW housing with a nitrile lip seal. The UHMW bearing eliminates metal-to-metal contact and associated problems of abrasion and electrolytic corrosion. They are 100% watertight. Their performance characteristics match those of other Tides Marine rudder ports in that they are quiet, smooth and vibration free.
