HIGH STRENGTH SLEWING BEARINGS
FOR BEARING POSITIONS UNDER HIGH LOADS
 

DrehverbindungenWe are experts with regard to rolling bearings in a wide variety of forms, including deep groove ball bearings, tapered roller bearings, cylindrical roller bearings, spherical roller bearings and needle roller bearings. Our product range also includes slewing bearings. The special characteristic of this large rolling bearing is that it can absorb axial and radial forces as well as tilting moments with just one bearing. Slewing bearings can take heavy loads and are quite versatile. There are many different design versions of this special rolling bearing. It can be driven via external or internal gearing or without gearing.


Slewing bearings can be used in many situations. Typical application areas include:

  • Construction equipment
  • Vehicles
  • Conveyor technology
  • Wind turbines
  • Medical technology





Because large rolling bearings must be able to withstand high loads, the requirements for the materials used are high. For the most part, these materials include

  • Steel and special steel in various alloys
  • Galvanized steel (corrosion protection)
  • Other metal alloys or plastics for bearing cages





In contrast to sliding bearings, rolling members reduce friction resistance in a rolling bearing. In the area of linear technology, ball screw drives function according to a similar principle. In slewing bearings, various rolling elements are used, with ball bearings or roller bearings as a possibility. There are single row and multiple row slewing bearings and cross-roll bearings. Multiple row bearings are suitable for use with heavier stresses. Slewing bearings are generally used at low speeds. Because this component is highly significant with respect to the safety of the entire design construction, reliable quality is very important and we guarantee it. Large rolling bearings often have to be adapted for special applications. For this reason, we offer customer-specific solutions in addition to our standard products.

Our engineers consult with you as necessary and support you in your selection or design of the right large rolling bearing. Even with slewing bearings there is a wide variety of possible solutions, e.g. space saving wire-race bearings, stabilizing slewing rings or robust four-point contact bearings. In addition, there are also cross-roll bearings, which run symmetrically and which are often used in machine tools or robots. Combined slewing bearings are suitable for use with high axial loads, so they are often used with rotary tables. Slew drives do not require much space for installation and are typically used to steer construction equipment. In addition to the slewing bearings, our product range also includes bearings for a wide variety of requirements in machinery, device and vehicle engineering. From housed bearing units and plummer blocks to spherical plain bearings and flanged bearings, we guarantee the highest quality, provide expert advice and realize your special requests.
