As a direct OEM replacement, this bearing cone meets the original design specifications Genie set for these machines, giving you confidence in the fit before the part ever leaves the box.

Key Features
- Genuine OEM Construction — Manufactured to Genie's original dimensional and load-rating specifications for the Outer Bearing Cone, ensuring proper taper geometry and surface hardness throughout its service life.
- Direct Drop-In Replacement — Designed to seat exactly as the original, with no rework or shimming needed to achieve correct bearing preload on the listed machines.
- Broad TZ and TMZ Compatibility — Confirmed fitment across TZ-50/30, TZ-50, TMZ-50/30, and TMZ-17/10 trailer-mounted articulating boom lifts.
- Structural Load Integrity — A properly seated bearing cone distributes rotational and axial loads evenly across the assembly; a worn or pitted cone introduces play and uneven loading that accelerates wear on surrounding components.
- OEM Part Number Traceability — Ordering by Genie part number 84957GT ensures you receive the exact cone specified for your model, eliminating guesswork when sourcing through a parts manual or service bulletin.
A bearing cone is the inner tapered ring of a tapered roller bearing assembly. It works together with the outer cup to carry both radial and thrust loads while allowing smooth rotation. When a bearing cone wears, develops pitting, or loses its surface hardness, it creates play in the assembly, generates heat, and can cause premature failure of the surrounding bearing components. Replacing a worn cone with the correct OEM part restores proper load distribution and smooth operation, protecting the integrity of the wider assembly on your TZ or TMZ boom lift.
