INA Spherical Plain Bearings


Maintenance-free spherical plain bearings

Maintenance-free spherical plain bearings are used as dry plain bearings for precise swiveling motion of parabolic troughs without stick-slip. Different ELGOGLIDEĀ® and PTFE sliding layers as well as designs with an additional anti-corrosion coating are available depending on the application and loads.


  • High load carrying capacity and low weight
  • Very suitable for slow and precise swiveling movements
  • Long rating life

Spherical plain bearings requiring maintenance

Bearings requiring maintenance must be lubricated due to the steel/steel or steel/bronze sliding contact surface. When designing the bearing support, it must be ensured that the bearing position can be adequately supplied with grease. These bearings are available as radial, angular contact and axial bearings.


  • Wide product range
  • All lubricants for initial greasing are tested before use in our in-house lubricant laboratory

Rod ends

Rod ends are used as linking elements in levers, linkages, and hydraulic and pneumatic cylinders. They support radial loads in a tensile or compressive direction. Rod ends are available with internal or external threads as maintenance-free variants or variants requiring maintenance.


  • Corrosion protection
  • Can be clamped or welded
