Self-lubricating plain bearing
GGB
These materials are generally designed to operate with marginal lubrication. DX and HX are most commonly provided with a uniform pattern of indents in the bearing surface that act as grease reservoirs.
The incorporation of PTFE filler in DS enables this material to operate dry when required. Due to the inherent lower friction of this polymer blend, it is usually supplied without indents.
The high-performance engineering polymer found in HX gives this material excellent temperature and chemical resistance combined with good load capacity and is particularly suited for operation under arduous conditions with oil lubrication.
