FRP Pads provide useful alternative to Teflon® and Fluorogold® Slide Bearings
Requirements can be related to:
- Thermal expansion or contraction
- Wind effected movement
- Machinery Vibration
- Seismic tremors
In any situation where a Slide Bearing is required an alternative that could be considered is the Fiber Reinforced Pad, or FRP.
Fig. 1
FRP Wear Pads are made of durable polyester resins that will act as a sacrificial bearing between two members, absorbing the wear as movement occurs. They offer the advantage of lower cost, simpler installation and easy replacement.
Shown in Figure 1 is the wear pad protecting a pipe riding on a flat surface. They can also be configured as Flat on Flat or Radius on Radius.
Typically, FRP Wear Pads will be fixed in place with epoxy. Mechanical anchors are not required. It is important the pads be located in areas with adequate access to allow for replacement. The lifespan will depend on the load and frequency of movement, operating temperature range and environment.
As applications become more demanding bonded Fluorogold® or Teflon® Slide Bearings may be required. These will offer a lower coefficient of friction and longer service life. Beyond that there are many variables that will affect the design of a bearing assembly such as operating temperature (Fluoroloc® to 500° F, Fluorotemp® to 1,000® F, Graphite to 3,000® F), exposure to elements, replacement requirements, etc.
