Polygon’s Extended Wear Surface (EWS) is made for high cycle and dithering, and low frictional values. It’s excellent for use in heavy equipment such as in construction, agriculture, mining, lifts and other rigorous equipment applications. Capable of going extended periods without maintenance, EWS resists contamination and wear.
The EWS bearing provides these benefits:
Maintenance free, never needs greasing
Use in high capacity, low friction conditions
Reliability and predictability.
No grease, means no dirt contamination
Maintenance-free operation for long time periods
Reduced maintenance visits
Preservation of equipment uptime.
Wear resistance and reliability in contaminated joint locations
Elimination of seals and machining costs
EWS has increased wear resistance and reliability in contaminated joint locations with small design envelopes. Seals and their machining cost can oftentimes be eliminated thanks to the increased contaminated environment performance.
