The lightweight and durable Polygon PolyLube sliding bearings made of fiberglass and epoxy composite are an excellent replacement for metal bushings that are subject to corrosion and temperature deformation.

Polygon Co. (Walkerton, Indiana, USA), a manufacturer of composite pipes, bearings and pneumatic cylinders, has developed a range of high-performance PolyLube plain bearings, which are made to order. Such bearings are suitable for use in construction and mining equipment, wheel loaders, excavators, compact tracked loaders, as well as in other types of machinery and equipment where articulated joints with a very long service life are required.

These bearings are made from continuously wound fiberglass, polymer resins, and polytetrafluoroethylene (PTFE) liners. This technology allows the production of thin-walled, durable and lightweight bearings.

With its high load-bearing capacity, low friction and corrosion resistance, Polygon composite bearings are self-lubricating, which reduces maintenance costs and extends service intervals.

In addition, these custom-made bearings easily replace existing metal bushings without replacing mating parts. Therefore, they can be used to improve the wear resistance of critical components and mechanisms without the need for a complete modernization of equipment.

Polygon experts say that PolyLube bearings are also suitable for agricultural machinery, including attachments, equipment for harvesting and harvesting, etc. Also, non-lubricated bearings working in forklift trucks and other warehouse equipment help maintain cleanliness inside warehouses, preventing possible contamination of the work area.
