The company claims that its products offer benefits such as high rigidity, high load-carrying capacities and reliable operation under extreme conditions.

In addition to standard bearings, engineered technologies for specific customer requirements can be provided.

Depending on the type and design of the power plant, suitable products may include slewing rings, angular-contact roller bearings, ballscrew drives, housed units, radial insert ball bearings, track rollers, plain bushes, spherical plain bearings and linear units.

Available products

  • Elgoglide plain bearings — designed for single-axis tracking systems, these maintenance-free systems offer high load-carrying capacities, particularly if very high loads are present on one side combined with swivelling movements
  • Elgotex plain bearings — also designed for single-axis tracking systems, these bearings are made of composite materials and are resistant to corrosive media; they offer continuously low friction and low-wear sliding characteristics
  • AXS angular-contact roller bearings — these are used in double-axis tracking systems, including solar towers and Dish Stirling power plants, where they offer high load-carrying capacities, rigidity and positioning accuracy
  • Complete linear drive systems — available from Schaeffler’s Linear Technology business unit, these include linear actuators, tables and modules and are suitable for the manufacture of solar collectors and photovoltaic modules as well as for solar tracking applications
  • Modular sealing systems — designed to cope with prevailing environmental conditions, these are used to optimise the functionality of rolling bearing surfaces and precision components that are subjected to high loads
