Description
RPB-J-1375 – Type J Rudder Port Bearing for 1 3/8 Inch Rudder Stock.
* Must send in Lock Nut or Cap Nut for Correct Thread Pitch and Size.
Thread Size: Choose from available sizes.
Tides Marine RPB TYPE-J is a retrofit unit which is used with existing bronze port bearings. Consisting of a one-piece UHMW plastic housing with nitrile lip seal, they were developed to replace the conventional stuffing box used on rudder ports.
The TYPE-J unit is virtually friction free, non-corrosive and maintenance free. Performance improvements include quieter, easier and smoother steering.
Note: To ensure correct thread size, please send Tides either the backing nut or the packing nut from your bronze rudder port assembly. We will measure the threads, machine the part and then return the backing nut or packing nut with your order.
Tides Marine RPB Type J Rudder Seals are designed to replace the flax packing and compression nut of existing bronze rudder ports. Consisting of a one-piece UHMW housing with a nitrile lip seal, the Type J is 100% watertight. It is not subject to electrolytic corrosion and provides quieter, smoother rudder system operation than the bronze stuffing box alternative.
Rudder Port Bearings Type J may be ordered online.
To determine the part number for your installation, measure the exact diameter of your rudder stock (.000″) and the diameter and thread size of the rudder port. Match these three measurements to a line in the chart below. Next, confirm that there is sufficient space to accommodate both the assembly’s diameter (Column B in the table) and height (Column C in the table on the Imperial and Metric pages).
If you are unable to match your installation measurements with those in Column A and C in the chart on the Imperial size page, simply call Tides Marine and we will machine a Type J to your specifications.
