What is a composite bearing?
Polygon's bearings feature three distinct components:
- Continuous glass fibers
- Polymer resin
- PTFE fabric liners
The fiberglass filament and epoxy resin combined form a very high strength backing. This precisely wound fiberglass structure allows for thin walled bearings (1/16" to 1/8"), reducing the size and weight of assemblies.
PTFE liners provide permanent lubrication unlike sintered metals which lose oils over time. Secondary lubrication is not necessary during start-up due to PTFE film transfer to the shaft.
Long life cycle
Testing shows wear under 0.006" after 1.6 million cycles, made possible by a woven structure of PTFE super-filaments with tensile strengths twenty times greater than PTFE resins. As a result, the bearing resists cold flow under high loads.
Handles industrial-level strain
PolyLube composite bearings support a load of up to 30,000 PSI while handling high radial and axial stresses. They resist high shock loading and impact fatigue due to their unique high strength continuous fiberglass backing. PolyLube bearings are ideal for high load operation in rotational and linear movements as well as in oscillation.
Exceptional dimensional stability
They exhibit high performance predictability over wide temperature ranges (+500 to -325°F).
Composite products are not our sideline; it is our profession. We engineer, design, manufacture, and test composite bearings and wear materials. We offer high temperature, high impact, food grade, insulating, corrosion resistant and numerous other specialty composite bearings.
