Environmental technology

PGslide® bearings are used as flat sliding bearings, spherical bearings or point rocker bearings in several sectors of the environmental technology. Some examples:

  • Waste incineration plants
  • District heating
  • Desulphurisation plants
  • DeNox-plants

Power plants

Such customers use the entire range of PGslide® sliding bearings up to connection temperatures of 600°C. PG Systemtechnik offers a wide range from flat sliding bearings to spherical and point rocker bearings with and without lift-off device made to measure. Samples of applications:

  • Steam producing
  • Steam cooling
  • Incinerators
  • Incineration chambers
  • Boilers and vessels
  • Air and gas preheaters
  • Electrostatic precipitators
  • Heat exchangers
  • Reactors
  • Condensers
  • Ventilators
  • Ash belt conveyors
  • Filters

Pipeline construction

In pipelines and pipework our PGslide® pipe bearings are widely used to overcome the expansion in the pipes by temperature shifts. Such bearings are used in:

  • Refineries
  • Hot and cold pipelines
  • Hot steam and hot gas ducts
  • Cooling water pipelines


Standard sliding bearings but very often custom-tailored solutions e.g. for lift-off forces or high temperatures are installed. Customers who use these bearings are:

  • Structural steel works
  • Structural concrete works
  • Car park decks
  • Airplane hangars
  • Exhibition halls
  • Steel tanks


In this relatively new product range special type bearings are used as guide systems in rails for transport systems – bearings have to be designed for 24/7 heavy-duty operation. Our references in successful operation:

  • PTS (People transport systems), people mover
  • Monorails

Other applications

The long-time know-how of PG Systemtechnik can be found in various „non-standard“ applications such as:

  • Concrete and steel bridges
  • Temporary bridges
  • Shifting technology
