Each slewing bearing type has different characteristics based on its design, which make it more, or less, appropriate for a given application.

For example, single row four-point contact slewing bearings have a simple and sturdy design that makes them cost-effective, while crossed cylindrical roller slewing bearings are used when accuracy and rigidity are key operational parameters or when zero operational clearance or preload is required.

Because several factors have to be considered when selecting a slewing bearing type, no general rules can be provided.

The information provided here are the most important factors to be considered when selecting a standard bearing type.

Factors include:

• accuracy

• magnitude and direction of loads

• permissible operating temperature

• vibration

• operating speed

• sealing

Selecting the appropriate slewing bearing can be a challenge, particularly if there are stringent technical, reliability or economic demands. In these cases, for example, it is advisable to consult the SoCare® application engineering service during the initial design phase. This service can do much more than help select a bearing. They can also provide expert advice in any of the following areas:

• design optimization

• lubrication systems

• sealing arrangements

To provide the SoCare® application engineering service with the information they need to help find the best technical solution for your application, SoCare® has developed a questionnaire, which can be found on in SoCare®-X series catalog.
