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.
G-Metal GSM yaw pucks offer wind turbines an excellent solution as brake pad material in both active and passive yaw braking systems.
G-Metal yaw pucks, as braking pad materials, maximizes the efficient and quiet operation of wind turbine yaw drive system preventing stick-slip (fog-horning) that can stop operations.
