New Aftermarket, Used & Rebuilt Swing Gear / Slew Bearings
The swing gear or slew bearing is the crucial interface that allows the upper structure of an excavator or crane to rotate smoothly over the undercarriage. A properly installed and maintained slew bearing ensures years of reliable rotation, while a worn or poorly matched bearing can cause vibration, structural stress and premature wear. We supply new and remanufactured slew bearings, swing gears and complete rotation assemblies for equipment from CAT, Komatsu, Volvo, Deere, Kobelco, Hitachi and more.
Our parts team verifies track compatibility by cross referencing OEM part numbers and confirming critical specs like pitch, sprocket count, guide style, tread pattern, and overall width and length. That fitment check matters because small differences in undercarriage design can cause premature wear, slipping, or frequent de tracking. Built for demanding work in construction, demolition, and site prep, these tracks are selected for durability and consistent performance. When you order from Best Equipment Sales Parts, you get help confirming the right track the first time, so your machine stays productive and your undercarriage stays protected.
