Filament-wound composite bearing with self-lubricating inner | Surface backed with a high-strength | Maintenance-free | With a sliding layer of PTFE with lubricant additives

Bearing properties

  • COM-KU®/M is a self-lubricating and maintenance-free plastic plain bearing. Using a heavy-duty glass fibre fabric combined with a selected binder resin helps to increase the mechanical properties, pressure further and wear resistance of this bearing type. The special lubricant additives and the PTFE in the sliding layer reduce the friction coefficient, optimising the wear behaviour and thus the material's service life as a dry sliding bearing.
