RPB-C-4000-00 - Rudder Bearing for a 4 Inch Rudder Stock.
Tides Marine TYPE-C Rudder Ports are for use in new construction or retrofits. They may be used with any hull material. They can be mounted into a built-up pad inside FRP or Wooden hulls or installed into a matching flanged tube in FRP or metal hulls. Unlike the typical custom fabricated assembly with separate bearings and packing, the TYPE-C combines both sealing and bearing functions in a cost effective housing.
It is an ABS-approved configuration and offers a substantial bearing surface-to-stock diameter ratio. The units consist of a single piece plastic housing with a nitrile lip seal.
The TYPE-C is 100% watertight, requires no maintenance and eliminates chatter and vibration resulting in quieter, smoother performance. It also eliminates the problems of metal-on-metal abrasion, electrolysis and corrosion
