Features:Wrapped Bushing is self-lubricating. It offers good frictional property, wear resistance and low noise. Note: Split line can not be used for bearing. Application:Solid friction oilless bushing can operate during a wide temperature range. Oilless sleeve bearings are most suitable for places where the self-lubricating properties of the material are required.
