Key Features
- Genuine OEM Dimensional Conformity — Manufactured to Genie's original material grade and thickness specifications, ensuring the washer seats correctly within the torque hub assembly.
- Direct Drop-In Replacement — Matches the original component geometry for a straightforward swap with no machining or modification.
- Broad Z-Series Compatibility — Fits a wide range of Genie Z-series articulating boom lifts, including the Z-30/20, Z-34/22 Bi-Energy, Z-45/22, Z-51/30J, Z-80/60, Z-135/70, and more.
- Wear Protection for the Hub Assembly — A correctly fitted thrust washer absorbs axial load and prevents metal-on-metal contact within the torque hub, extending the service life of surrounding components.
- Supports Drive System Integrity — A worn or missing thrust washer allows unwanted play in the hub, which can lead to accelerated wear of adjacent parts and uneven drive performance.
A thrust washer is a flat bearing component positioned within a rotating assembly to manage axial — or side-to-side — load between moving parts. In the torque hub of a Z-series articulating boom, it sits between rotating and stationary surfaces to reduce friction and keep components properly aligned under load. When a thrust washer wears thin or fails, metal surfaces make direct contact, generating heat and accelerating damage to the hub assembly. Replacing a worn washer promptly with the correct OEM part restores proper clearances and protects the integrity of the drive system.
