Description
Maximize rotational efficiency and reduce power loss in your commercial fleet with the genuine FAG Heavy Duty Commercial Vehicle Deep Groove Ball Bearing. Engineered specifically for heavy-duty commercial trucks, auxiliary drive systems, gearboxes, and engine accessories, this OE-grade bearing supports simultaneous radial loads and moderate axial forces in both directions under high-speed operation. Worn raceways, fatigue flaking on steel balls, or degraded seal lips cause abnormal metallic whining, excessive shaft play, lubricant leakage, and sudden accessory component lockups. This original FAG deep groove ball bearing solves those mechanical failures directly. It features high-purity 100Cr6 bearing steel, super-finished raceway grooves, reinforced steel or synthetic cages, and high-performance contact seals to deliver low friction torque, whisper-quiet running, and uncompromised driveline reliability in demanding transport operations.
Technical Parameters
| Category | Specifications & Technical Details |
| High-Purity Vacuum-Degassed 100Cr6 Bearing Steel | We manufacture the rings and steel balls from high-purity quenched bearing steel. As a result, they contain very few internal inclusions. Moreover, they deliver strong resistance to rolling fatigue spalling and high compressive strength. |
| Super-Finished Raceways & High-Grade Steel Balls | We micron-level super-finish the inner and outer ring raceways. Consequently, this greatly reduces friction resistance and noise. Notably, it meets the low-power consumption requirements of continuous high-speed operation. |
| Optimized Dual-Lip Sealing Technology | We offer specialty NBR / FKM dual-lip rubber seals (2RS) or metal dust covers (2Z). Therefore, they effectively block dust particles and moisture intrusion while preventing grease leakage. |
| Pre-Lubricated High-Performance Synthetic Grease | We pre-fill the bearing with long-life, high-performance synthetic grease. It withstands extreme operating temperatures from -40°C to 150°C. Additionally, it offers excellent oxidation resistance and resistance to water washout. |
| OEM-Grade Precision Tolerance & Internal Clearance | We produce strictly to ISO / DIN standards and offer C3 / C4 grade precision internal clearance. As a result, the bearing runs smoothly without seizing under high-temperature thermal expansion. |
Applicable Car Brands & Models
Common warning symptoms include:
High-Pitched Whining or Humming Noise: Excessive noise originating from engine accessories or gearbox shafts that increases in pitch with engine RPM.
Excessive Shaft Play or Wobble: Noticeable radial or axial looseness in belt pulleys, alternator shafts, or gearbox output shafts.
Overheating Around Bearing Housing: High operating temperatures detected on accessory housings caused by friction buildup inside worn raceways.
Grease Leakage or Discolored Residue: Darkened grease or brown rust powder leaking past damaged rubber seals.
Premature failure is typically caused by improper installation (using hammers instead of press tools), excessive belt tension, thermal overload, or moisture/dust contamination penetrating compromised seals.
Yes. Sealed FAG deep groove ball bearings (2RS designation) are factory-filled with precisely metered synthetic grease and sealed for life. They require no additional greasing maintenance throughout their operational lifespan.
Our 1-year warranty covers all raceway spalling, ball fatigue fracture, cage damage, seal manufacturing flaws, and non-artificial mechanical failures under normal operating conditions. If a bearing fails within 12 months, we provide prompt replacement or warranty processing upon inspection.
