INA Slewing Rings

INA slewing rings are used in solar power plants for the precise alignment of particularly large reflectors and collectors, for example in double-axis tracking systems with two separate drives. In the case of separate drives, slewing rings are used in the bearing supports of azimuth axes.


INA slewing rings are known worldwide as premium products in the field of rolling bearing technology. A single bearing can reliably support radial, axial and tilting moment loads. It is therefore possible in many cases to replace bearing supports comprising a combination of radial and axial bearings by a single bearing, despite the high loads involved. This reduces, in some cases considerably, the costs and work required in the design of the adjacent construction and the fitting of bearings.

Slewing rings are sealed on both sides and lubricated with high-quality lubricating grease. They can be lubricated via lubrication nipples. The bearing rings are supplied without gear teeth or, in order to achieve simple drive solutions, are available with external or internal gear teeth. Customer-specific special solutions are also possible. INA slewing rings are available as single or double row four-point bearings as well as crossed roller bearings.
