A journal bearing is a machine element generating a completely seperating oil film between shaft and bearing. The oil film is the load bearing element in this arrangement.
The body of a journal bearing made by our company mostly consists of steel. In individual cases it can be made of copper alloy. To enable a start of the machine from standstill without damaging the shaft, a layer of a relatively soft babbitt based on tin and lead is applied on the bearing surface.
There is no contact between shaft and bearing during operation. Therefore, during steady state operation, the journal bearing is in principle wear-free.
The journal bearing system is a functional unit that consists of the component journal bearing in an adequate environment with bearing housing and oil supply. Parts of this functional unit are, if necessary, also elements like sealings, oil pumps, pipings, cooler, instrumentation and others. The complexity of this functional unit is often larger than the comlexity of the journal bearing itself.
GTW is your competent and professional partner for journal bearings and journal bearing systems in plant and mechanical engineering. We do not just see ourselfs as a component supplier, but also as an advisive partner for realisation of complex projects. With own ideas and suggestions we help to create your success.
The customers appreciate our expertise and our orientation on quality in the field of journal bearings. We are certified according to ISO 9001. The European market leaders of drive engineering belong to our customers (references).
Some of our most significant innovations are a patented and successfully applied loss-reduced journal bearing and a range of thermally self-sufficient bearing systems without external ancillary units.
Appliation of our loss-reduced journal bearings for instance allows for power plant operators to reduce bearing losses by up to 50% and thereby aids in providing a more efficient and environmentally friendly energy generation.
Thermally self-sufficient bearing systems simplify their application by abandoning accident-sensitive and expensive ancillary units, which is why they have come to replace conventional journal bearing systems in many appliations.

Product portfolio

Our product portfolio includes journal bearings and components thereof for plant and mechanical engineering in the following areas:

  • Generation of energy
  • Conversion of energy
