The Genie 52778GT is a genuine OEM Flanged Bearing,.376ID (20424GT) built for Genie S series telescopic boom lifts and Z series articulating boom lifts. As a direct OEM replacement, this bearing meets the original design and dimensional specifications Genie engineering requires for these machines. Cross-reference part number 52778GT against your machine's parts manual to confirm it is the correct bearing for your unit before ordering. Compatible models include the S-40, S-45, S-80, S-85, Z-60/34, and Z-34 IC.
Key Features
- Genuine OEM Dimensional Conformity — Manufactured to Genie's exact .376ID specification, ensuring the flanged bearing seats and loads correctly within the original bore without modification.
- Direct OEM Replacement — This bearing installs in place of the original component 20424GT, preserving the correct bearing interface and load path in the assembly.
- Broad Boom Lift Coverage — Fits Genie S series telescopic booms (S-40, S-45, S-80, S-85) and Z series articulating booms (Z-60/34, Z-34 IC), covering multiple platform configurations in the Genie boom lift lineup.
- Smooth Pivot and Rotation — A correctly seated flanged bearing allows pivot points and rotating joints to move freely under load, reducing wear on mating components and maintaining consistent motion throughout the boom's range.
- Structural Integrity at Pivot Points — On aerial boom lifts, bearing wear at critical pivot joints can introduce play that affects platform stability. Replacing a worn bearing with the correct OEM part restores the tight tolerances these lifts require for safe operation at height.
A flanged bearing supports rotational or oscillating movement at a pivot or joint while the flange face acts as a built-in locating surface, preventing axial migration and keeping the bearing correctly positioned within its housing. On boom lifts, bearings of this type are commonly found at articulation points, boom-section pivots, and linkage joints where controlled movement under load is essential. When a bearing wears, it introduces looseness at the joint, which can cause uneven movement, accelerated wear on surrounding hardware, and a loss of the precise control the operator expects. Replacing a worn bearing promptly with the correct OEM part restores smooth, controlled motion and protects the integrity of the surrounding assembly.
