Ceramet 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. Sintered materials provide reliable and high-performance no-grease solutions.
Ceramet CER.SM yaw pucks offer wind turbines an excellent solution as brake pad material in both active and passive yaw braking systems.
Ceramet yaw pucks, as braking pad materials, maximize the efficient and quiet operation of the wind turbine yaw drive system preventing stick-slip (fog-horning) that can stop operations.
