ADVANTAGES

  • Maintenance-free service
  • Inexpensive, easy and fast to replace
  • Maximal uptime and reduction in maintenance cost
  • Suitable for higher loads
  • Allowing for enormous variability in shapes and sizes, solutions taking less space possible
  • Great emergency running properties
  • Performing particularly well in high-temperature environments up tp 650oC
  • No moisture absorption, maximum dimensional accuracy and stability
  • Suitable for wide range of operating speeds

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.
