DX Bushing has a similar material structure with DU Bushing. It’s triple layer composite material which consists of a steel backing, sintered porous bronze layer and POM as surface layer. DX bearing is designed to fill the gap between dry and lubricated type bearings. DX Bush ensures smooth operation over an extended period of time. Once lubricated upon installation only, minimum lubrication is needed from then on at regular intervals. Our PVB020 series belongs to DX bushing.
