G-Metal self-lubricating plain bearings and bushings with a sintered sliding layer are especially suitable for continuous operations in a demanding 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.
