GGB DU™ Cylindrical Bushes - Inch Size 20DU28

Our metal-backed, PTFE-based (polytetrafluoroethy lene) polymer bearing materials have a common structure, consisting of a metal backing bonded to a porous bronze sinter layer. This bronze sinter layer is impregnated and overlaid with the filled PTFE bearing lining. The metal backing provides mechanical strength, while the bronze sinter layer provides a strong mechanical bond between the backing and the bearing lining. This construction promotes dimensional stability and improves thermal conductivity. These polymer bearing linings, being predominantly PTFE, offer exceptionally low friction.
