What is a composite bushing?

Polygon's bushings 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 bushings (1/16" to 1/8"), reducing the size and weight of assemblies.

Greaseless

PTFE liners provide permanent lubrication unlike sintered metals which loose 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 bushing resists cold flow under high loads.

Handles industrial-level strain

PolyLube composite bushings 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 bushings 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 (±325°F).

Singular focus

Composite products are not our sideline; it is our profession. We engineer, design, manufacture, and test composite bushings and wear materials. We offer high temperature, high impact, food grade, insulating, corrosion resistant and numerous other specialty composite bushings.
