Radial Carrier Bearing and Packing Gland as Installed

This combination radial, carrier bearing and packing gland is integrated into the steering gear tiller, and provides a very compact and minimum maintenance arrangement. Side loads from the rudder, and weight of the rudder and rudder stock, are taken up by large area self-lubricating proprietary synthetic bearing liners. On installation, and occasionally thereafter, a small amount of greasing is sufficient to provide low friction and minimal wear. This unique bearing material has been tested in many installations for over 14 years, with no bearing replacement necessary so far. Eventual replacement is very easy, as the bearing liner is easily removed and replaced without the use of heavy hydraulic presses or jacks.

The packing gland protects against sea water intrusion and has large, easy to access gland ports. All parts exposed to sea water are made of stainless steel and manganese bronze. Scoring, bearing damage and high friction, as experienced with bronze bearing liners, is eliminated. The compact design allows fitting in extremely restricted steering compartments.
