MG-CR Filament wound plastic self-lubricating bearings

Product Detail
High strength glass fiber with epoxy resin baked with PTFE and special fiber as bearing lining, the back material provides high load capacity and bearing lining ouers low friction under dry condition. Therefore, this special structure ouered an outstanding anti-wear feature and anti-impact performance,suitable for high load with high corrosion resistance application like lifting machinery, logistic machinery, agricultural machinery, and port machinery etc.
