When
the practical limits of steel-reinforced elastomeric bearings are exceeded,
PTFE slide bearings are the choice of many designers. The steel-reinforced
bearing pad is topped with a steel plate that is permanently vulcanized
to the elastomer. A PTFE element is then either bonded to the surface
of the plate or partially recessed into the plate. The PTFE can be
sized smaller than the bearing and can be dimpled to improve the coefficient
of friction. In application, the PTFE element slides against a polished
stainless steel upper surface, which is welded to the underside of
a steel plate attached to the supported member. PTFE slide bearings
allow for the design of larger longitudinal and transverse movement than with a standard
laminated pad.
