Due to engine downsizing, more and more energy is released in the form of vibrations at the crankshaft. A system is required which can absorb these huge vibrations and torsional oscillations. 

Friction bearings made of tribologically-optimized polyamides from KKI for viscous torsional vibration dampers fulfill the requirements. Viscous torsional vibration damper systems can effectively minimize vibrations and torsional oscillation in low-consumption and emission-reduced engines for the automotive industry. Such systems are fully production-ready.

Viscous torsional vibration damper systems minimize vibrations and torsional oscillations. Effective, low-consumption and emission-reduced engines for the automotive industry are fully production-ready.

Simultaneously acting radial and axial loads usually require the combination of two bearing types. This means increased installation space, since each bearing must be designed according to the requirements.

Here too, it took a bright mind to come up with the solution. A clever engineer devised a combined axial-radial bearing that is essentially an entirely new machine element. The combination of radial and axial bearing in a single component significantly reduces space requirements. Forces in both radial and axial direction are absorbed by the build-up of a lubricating film between the bearing halves. The effect is reinforced due to the tilting of the bearing, thus enabling extremely high bearing forces. The assembly is almost identical to the installation of a deep groove ball bearing. Minimum lubrication by any medium (except air) is required.

The development of a new bearing element for the different requirements such as high speeds, extreme robustness and smooth running. A bearing type that is frequently used in the new E- mobility applications.

The solution is our new machine element called "Hydrodynamic 3D-Plain Bearing". The new "Hydrodynamic 3D-Plain Bearing" withstands bearing loads that are absorbed by axial needle bearings, thrust washers or plain bearings.
