New Aftermarket Swing Bearings

excavator swing gear

A swing bearing, or slew ring, is the rotating joint between the upper and lower frame of an excavator. It is an essential part of the machine as it allows for 360-degree rotation on the top structure, while the bottom structure remains stationary. The assembly of a swing gear may vary based on make and model of your machine, but the main components remain the same.
