Engineered to be maintenance-free

POLYGONCOMPOSITES.COM

Eliminate secondary lubrication systems.Polygon bearings are engineered to be self-lubricating

and maintenance-free. With excellent load capacities,

low friction, resistance to corrosion and more, Polygon

composite bearings make heavy equipment operate

easier, longer and better.

Made to order.With multiple configuration options and tailored

designs, we can help you determine the best fiber

architecture, resin formulations and finishing for

your project. It’s a made-to-order solution for

critical applications.

Features & BenefitsApplicationsTypical products and applications:

• Excavators

• Mini & micro excavators

• Bulldozers

• Backhoes

• Skid Steers

• Wheel loaders

• Aerials & lifts

• Agricultural equipment

Commonly Used BearingsThis selection of Polygon bearings is often the starting point for designing the tailored

component that is engineered for your project.

MRP BEARING

For applications that require

high load capacity, low

friction and minimal wear

characteristics.

EWS BEARING

Capable of going extended

periods without maintenance,

this bearing resists

contamination and wear.

GLASS TAPE BEARING

The wear surface in the bearing

provides reduced stick-slip and

smooth motion, especially in

lower pressure applications.

Self-lubricating Maintains peak performance throughout the product life; minimizes maintenance costs and improves productivity

DurableWill not rust or corrode; for use in dry/dusty conditions and wet, dirty or corrosive environments

Low friction/low wearResistant to impact fatigue and ensures a long service life

Flexible design Allows for a tailored product that optimizes performance and extends bearing life

Unique compositionUnique woven filament is resistant to corrosion, moisture, seizure, chemicals and fretting

Temperature resistant Operates in temperatures from –325° to 325°F

High strength/low weight High strength to weight ratios

Thin walls As thin as 1.5mm; low coefficient of friction and high load-bearing capacity

Long service life The bearing structure ensures almost constant coefficients of friction and wear rates

Simplified assembliesNo grease zerks; shaft/pin lubrication accommodation; minimized grease contamination
