Normally, a slide bearing consists simply of two pads of PTFE sliding against each other; for very high-pressure applications, a single pad may be used to counter face a polished stainless steel plate. The assembly is manufactured so that one pad (generally the top pad) is larger than the other by an amount in excess of the expected movement, so keeping the contact area constant throughout the cycle of motion.
TECHNICAL ADVANTAGES OF FLUOROGLIDE® PTFE SLIDE BEARINGS
PTFE has the lowest coefficient of friction of any known solid 'engineering material' including lubricated metal.
There is no stick-slip action.
Fluoroglide® slide bearings have near infinite life, since chemicals and weather have no effect on PTFE - moisture absorption is less than 0.01% even under icing conditions or immersion, and the material is chemically inert.
No maintenance is required. Fluorinoid® PTFE will never cold weld to itself and therefore requires no lubrication.
Fluoroglide® slide bearings are easily installed, either pre-assembled or on site.
Fluoroglide® slide bearings are less bulky than alternative assemblies.
There is no possibility of fatigue failure.
Electrical and thermal insulation minimize galvanic corrosion and heat transfer.
Vibrations are dampened.
Small particles which may become embedded do not cause binding of the surfaces.
Fluoroglide® slide bearings can accommodate some misalignment in construction without setting up stress corrosion along a leading edge, as can occur in conventional bearings
PTFE SLIDE BEARING APPLICATIONS
Pipelines
Heat exchangers
Concrete decks
Oil & water transportation
Storage tanks/plants
Buildings - multi-story car parks, civic centers etc.
Subsea pumping stations
Pedestrian walkways
