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
