Slewing Ring Bearing Features

Slewing ring bearings are good options for a wide range of heavy-duty mechanical equipment while also providing design flexibility. They can withstand a variety of loads, including axial, radial, and tilting moments for many varied applications.


The application, weight, and intended function of the equipment all influence the variables of slewing ring bearings. Variable characteristics may include:


• Single, double or triple row structure

• With or without gear teeth, internal or external gear teeth

• Ball, cross roller, or combination bearing designs

• Size and location of mounting hole patterns

• Lubrication holes are available

• Preloading options are available as well as variations in clearance

If those options don't meet your need, our engineer team are ready to help you with further customization.
