Solid sintered bronze bearing | Maintenance-free | With uniformly embedded solid lubricant in the bronze or iron matrix

Bearing properties

  • GAP-MET®/M is a maintenance-free plain bearing. However, oil or grease lubrication is possible. High load capacity and strength for all slow movement types, suitable for contaminated environments, no moisture absorption, good chemical resistance and good temperature resistance. The parts are mechanically reworkable.


  • Self-lubricating sliding material, powder metallurgically produced. Homogeneous microscopic fine distribution of the lubricant in the bronze or iron matrix.
