ADVANTAGES

  • Maintenance-free service
  • Inexpensive, easy, and fast to replace
  • Suitable for intermittent movements
  • Allowing for enormous variability in shapes and sizes
  • Suitable for dirty environment
  • High static and dynamic load
  • No pollution due to lack of lubrication

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.
