Description
Maximize power density and ensure smooth rotational performance in your commercial vehicle driveline with the genuine FAG Commercial Vehicle Needle Roller & Cage Assembly. Engineered specifically for heavy-duty commercial transmissions, planetary reduction gearboxes, and auxiliary drives, this OE-grade bearing assembly provides maximum radial load capacity within an ultra-compact radial space. Broken cage pockets, surface pitting on rollers, or thermal seizure cause severe gear clashing, transmission noise, excessive heat generation, and catastrophic gearbox failure. This original FAG needle roller and cage assembly solves those mechanical transmission failures directly. It combines high-precision 100Cr6 steel rollers, a rigid fatigue-resistant cage, and an optimized roller profile to deliver uniform load distribution, minimal friction torque, and uncompromised driveline reliability in demanding transport operations.
Technical Parameters
| Category | Specifications & Technical Details |
| High-Density Needle Roller Configuration | We use deep-hardened 100Cr6 high-carbon chromium bearing steel needles. They deliver extremely high radial load capacity and rigidity within a very small radial cross-section. |
| Optimized Crown Profile Needle Rollers | We precision-grind the needle ends with a crowning profile. This eliminates edge stress caused by slight axis deflection under heavy load. Consequently, it extends fatigue life. |
| High-Strength Guided Roller Cage Architecture | We build a compact, high-fatigue-strength cage. It precisely guides the needles in parallel even at high speed and under high-frequency impact. As a result, it reduces friction resistance and heat buildup. |
| Ultra-Precise Radial Sorting Tolerance | We control needle diameter tolerances within the same group to micron level. Therefore, needles distribute load evenly around the full circumference. Moreover, this prevents individual needle overload wear. |
| Special Surface Anti-Wear Finish | We apply high-grade phosphating and heat treatment to the needles and cage. This delivers strong anti-seizure, false Brinell resistance, and resistance to high-temperature lubrication degradation. |
Applicable Car Brands & Models
Common warning symptoms include:
Transmission Whining or Grinding Noise: High-pitched gear noise or grinding sounds coming from the gearbox, especially under load or in specific gear ratios.
Hard Shifting or Gear Jumping: Difficulty engaging gears or gears popping out of mesh due to misalignment caused by worn needle assemblies.
Excessive Transmission Heat: Gearbox operating temperature rises significantly above normal limits due to increased friction torque inside the bearing assembly.
Metal Shavings in Gear Oil: Magnetic drain plugs collect fine metallic particles or broken cage fragments during routine maintenance.
Failure is typically caused by insufficient or contaminated gear oil, extreme thermal overload, or improper axial shaft alignment. Lack of clean lubrication causes metal-to-metal contact, leading to spalling on the rollers and cage fatigue failure.
Yes, if the shaft journal and gear bore raceways remain within OEM specification limits (free of pitting, scoring, or thermal discoloration). If raceways show wear, replace the complete bearing set or recondition the shaft to prevent rapid damage to the new needle assembly.
Our 1-year warranty covers all material spalling, structural cage breakage, manufacturing dimensional flaws, and non-artificial mechanical failures under normal operating and lubrication conditions. If an assembly fails within 12 months, we provide prompt replacement or warranty processing upon inspection.
