ADVANTAGES

  • Maintenance-free service
  • Suitable for a wide range of movements
  • Allowing for enormous variability in shapes and sizes
  • Performing well in high-temperature environments up to 650°C

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.
