ADVANTAGES

  • Maintenance-free service
  • Inexpensive, easy, and fast to replace
  • Suitable for intermittent movements
  • Allowing for enormous variability in shapes and sizes
  • High load endurance that offers high wear resistance
  • Clean working environment
  • Removing fire hazard by eliminating of grease
  • High number of cycles due to special self-lubricating sliding surface resulting in low wear rate
  • Tight tolerance and low wear to guarantee precise closing of the machine
  • Optional lubricating pockets for grease and oil lubrication are available

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.
