Important remark: The above-mentioned material properties, in particular friction coefficients, are not assured properties. they are to be used only as guidelines for the selection of materials.
G-Metal self-lubricating plain bearings and bushings with a sintered sliding layer are especially suitable for continuous operations in a wet environment. Sintering technology allows for the construction and manufacturing of a wide range of complex shapes with consistent self-lubricating properties throughout the whole lifecycle of critical moving parts. G-Metal based materials provide reliable and high-performance no-grease solutions.
