Technical Specifications: Premium Heavy-Duty Fan Support Ball Bearing (996519 / VOE996519)Premium Heavy‑Duty Fan Support Ball Bearing (996519 / VOE996519) — Cooling System Rotational Support
Our Premium Heavy‑Duty Fan Support Ball Bearing (Part Number: 996519 / VOE996519) is a precision deep‑groove bearing supporting the engine cooling fan assembly. Installed inside the fan hub bracket, it withstands high radial‑axial loads and continuous high‑speed rotation. With low‑friction operation under high engine‑bay temperatures, it stabilizes fan rotation, eliminates shaft wobble and ensures reliable radiator cooling performance to prevent engine overheating.
Core Technical Advantages
High‑Carbon Chromium Through‑Hardened Bearing Steel: Strict heat‑treated steel resists fatigue, spalling and damage caused by long‑term belt tension loads.
High‑Temperature Synthetic Pre‑Grease: Shear‑stable high‑performance lubricant avoids oil leakage and thermal degradation under extreme under‑hood heat.
Dual‑Lip High‑Temperature Sealing Shields: Double‑sided reinforced seals retain grease and block dust, moisture and construction‑site contaminants.
Precision‑Ground Raceways & Rolling Elements: Ultra‑smooth finishing ensures quiet vibration‑free rotation and prevents shaft jamming during continuous operation.

Professional Tech Note:
Worn fan bearings produce abnormal noise, fan wobble and uneven belt wear. Seizure may break fan blades, damage the radiator or snap the serpentine belt (22089205), causing water‑pump (21404502) failure and engine overheating. Inspect the fan hub, tensioner and belt alignment during replacement. Verify machine Serial Number (S/N) and engine model for exact dimensional matching prior to bulk ordering.
