Before the use of metal polymer plain bearings, grease was applied to boot, bonnet and door hinges to act as a lubricant between the pin and the housing during the opening and closing of the hinge.
The disadvantages of this greased solution are:
The majority of today’s passenger vehicles, vans and trucks are fitted with hinges that use self-lubricating GGB DP4 metal polymer plain bearings.
The structure of GGB DP4 composite bearings consists of a strong steel backing, to which is bonded a porous bronze sinter interlayer impregnated and overlaid with a PTFE enriched wear resistant bearing layer.
This highly resistant composite bearing structure can withstand specific loads of up to 250 MPa / 36 000 psi and temperatures up to 280°C / 536°F which exceeds the curing temperatures of the cataphoretic paint process.
In automotive hinges, the excellent self-lubricating properties of GGB DP4 metal polymer composite bearings offer the following benefits:
