Polygon IBS Material Composition
The fiberglass filament and epoxy resin combined form a very high strength backing. This precise filament wound fiberglass structure allows for thin walled bushings (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.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.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 filament wound fiberglass backing. PolyLube bearings are ideal for high load operation in rotational and linear movements as well as in oscillation.
