Description
Maximize load-bearing capacity and ensure long-lasting wheel-end stability across your commercial fleet with the genuine SKF Heavy Duty Commercial Vehicle Tapered Roller Bearing. Engineered specifically for heavy-duty commercial truck wheel hubs, axle differentials, and transmission final drives, this OE-grade tapered bearing supports heavy combined radial loads and simultaneous axial forces in a single direction. Pitted raceways, spalled steel rollers, incorrect pre-load adjustment, or lubricant breakdown cause excessive wheel hub play, high-pitched bearing roaring, high operating temperatures, and sudden axle seizure. This original SKF tapered roller bearing solves those mechanical failures directly. It features premium case-hardened 100Cr6 bearing steel, optimized logarithmic roller contact geometry, a precision steel cage, and heavy-duty seal compatibility to deliver uniform stress distribution, ultra-low friction torque, and uncompromised transport reliability in demanding fleet operations.
Technical Parameters
| Category | Specifications & Technical Details |
| Logarithmic Profile Roller Geometry | We precision-profile the tapered roller generatrix to a logarithmic curve. This completely eliminates edge stress under heavy-load deflection or axial impact. As a result, it greatly improves spalling resistance life. |
| High-Purity Vacuum-Degassed 100Cr6 Steel | We manufacture the inner and outer rings and rollers from high-purity vacuum-degassed bearing steel. The surface achieves extremely high hardness and wear resistance, while the core retains good toughness to withstand severe road impact. |
| Separable Adjustable Clearance Architecture | We use a separable tapered inner and outer ring design, with the inner ring assembly independent from the outer ring. This makes hub and axle press-fitting and removal easier. Additionally, technicians can precisely set optimal preload by adjusting the lock nut. |
| High-Strength Rigid Steel Roller Cage | We adopt a heavy-duty reinforced steel cage. It evenly separates each tapered roller and keeps them perfectly parallel even at high speed and under high friction load. |
| Optimized Contact Angle & Axial-Radial Ratio | We design a precisely matched contact angle. It simultaneously carries huge radial loads and one-direction axial thrust. Therefore, it perfectly handles the lateral stress of heavy truck sharp cornering and hill climbing. |
Applicable Car Brands & Models
Common warning symptoms include:
Deep Roaring or Humming Noise: A constant low-pitched rumbling noise from the wheel end that increases in volume and pitch with vehicle speed.
Excessive Wheel Hub Play: Noticeable looseness or wobbling when shaking the tire vertically or horizontally while lifted on a jack.
Abnormal Hub Temperature: The wheel hub housing feels significantly hotter than neighboring wheels after driving on the highway.
Grease Leakage or Metal Particles: Discolored gear oil or dark grease mixed with fine metallic flakes leaking past wheel-end oil seals.
Premature failure is typically caused by incorrect bearing preload adjustment (too tight causing overheating or too loose causing shock damage), contaminated gear oil or grease, and water intrusion through damaged hub seals.
Yes. Unlike sealed ball bearings, tapered roller bearings require precise axial end-play or preload adjustment using a torque wrench and dial indicator according to OEM specifications to ensure correct operating lifespan.
Our 1-year warranty covers all raceway spalling, roller fatigue fracture, cage damage, manufacturing dimensional 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.
