Complete drives are becoming increasingly important to many customers as a space-saving solution. They consist of geared rotary bearings and corresponding pinions, which are assembled in compact housings. In addition, the rotary drive can be fitted with a suitable drive motor, optionally as an electric or hydraulic motor . As a result, we can provide compact assembly units for a variety of applications, which can help customers avoid purchasing individual components.
In addition to Dual Volleyball Slewing Bearings as Eight Point Contact Bearings, we also supply Dual Volleyball Slewing Bearings as Double Axial Ball Bearings. This type is widely used in transport technology.
For load combinations with high tilting moments and low axial loads, and for slewing bearings with suspension, the bearing capacity of the bolted connection usually determines the size, not the raceway geometry. Special solutions are provided to avoid size increase, such as increasing the number of fastening screws or increasing the aperture. When forwarding load conditions, we check the bolt connections from the start and propose solutions if necessary.
In general, it is not possible to use plastic gaskets to separate rolling elements of rotary bearings that withstand high loads, torques or rotation speeds. In this case, we offer a cage design. These are available in brass or complete steel construction. Depending on the specific application, the cage is inserted as a whole or as a segmented structure .
