The Genie 99581GT Swing Bearing is a genuine OEM component built for TZ-50/30 and TZ-50 trailer-mounted articulating boom lifts. Sourced directly through Genie's OEM supply chain, this bearing delivers the exact dimensional and load specifications required for correct operation on these machines. Cross-reference part number 99581GT against your machine's parts manual to confirm it is the right item for your unit before ordering.
Key Features
- Genuine OEM Construction — Manufactured to Genie's dimensional and load-bearing specifications, ensuring the bearing seats, races, and mounting interfaces match the original component exactly.
- Direct Replacement Fit — Engineered to drop into the same mounting position as the original, allowing a straightforward swap without machining or custom fitting.
- Confirmed Fitment for TZ Series Booms — Fits TZ-50/30 and TZ-50 trailer-mounted articulating boom lifts, keeping you on the correct part the first time.
- Smooth, Consistent Rotation — A sound swing bearing allows the boom's upper structure to rotate freely and evenly. A worn or compromised bearing introduces play, binding, or uneven movement that degrades machine control.
- Operational Safety — The swing bearing is a structural interface between rotating and stationary sections of the boom. Maintaining it in good condition is essential to safe, controlled boom positioning at height.
A swing bearing is the large-diameter bearing assembly that supports and enables rotation between the upper rotating superstructure and the lower base or turntable of a boom lift. It carries both the weight of the boom assembly and the dynamic loads generated during rotation and lifting, while allowing smooth, controlled 360-degree slewing. When a swing bearing wears, operators may notice roughness, play, or noise during rotation; if left unaddressed, wear can progress to the point where structural integrity and precise boom positioning are compromised. Replacing a worn bearing with the correct OEM part restores proper function and helps keep the machine operating safely.
