Friction Free Bearing

As a result of investigating a heavy-duty bearing material with superior low
friction properties, the F.F.B. was developed in 1982 combining
technologies from bearings made with P.T.F.E. and synthetic rubber. With
over 19 years of actual operational experience for F.F.B. on naval vessels
and high speed, long-distance cruising ferries, F.F.B. has proven the most
effective bearing when conformity to the strict demands of vessels is
considered. Heavy-duty, low vibration, low noise levels, maximum fuel
economy and long life with less maintenance cost.

Construction is a Three Layer Structure:
A special compound elastic rubber is sandwiched between Poly-tetra Fluor
Ethylene and the outer metal shell. The three layer structure solves an issue
that the bearing must be flexible against a poor alignment and yet be
excellent against wear which are incompatible with each other.

Long Life:
The superior frictional characteristics of F.F.B. minimize both shaft sleeve
and bearing wear. Many F.F.B. are still working over 15 years or more in
good condition without any replacement and with little shaft liner wear.
