GGB DP4
GGB DP4 is part of the GGB range of metal-polymer (ptfe) composite plain bearings — with engineered-plastic (solid polymer), fibre-reinforced filament-wound composite, and self-lubricating metal/bronze families. The lead-free, high-PV evolution of DU — the RoHS-compliant dry-running replacement for oil-impregnated sintered bronze, cross-referencing Bushingo's BP25. Comparable to lead-free metal-polymer grades from Kolbenschmidt Permaglide and other PTFE/bronze bearing makers.
