Description
Eliminate wheel hub runout and maintain rigid axle alignment across your commercial fleet with the genuine SKF Commercial Vehicle Tapered Roller Bearing Cone & Cup Set. Engineered specifically for heavy-duty commercial truck wheel hubs, drive axle differentials, and transmission pinions, this OE-grade matched bearing set combines a precision-ground cone (inner ring with rollers and cage) and a matching cup (outer ring). Pitted raceways, spalled steel rollers, mismatched cup-and-cone tolerances, or lubricant contamination cause severe wheel chatter, deep roaring noises, excessive hub heat, and sudden axle lockups. This original SKF tapered roller bearing cone and cup set solves those mechanical failures directly. It features premium high-purity 100Cr6 bearing steel, logarithmic roller contact geometry, a heavy-duty steel cage, and micro-finished raceway surfaces to deliver uniform load distribution, ultra-low friction torque, and uncompromised transport reliability in demanding fleet operations.
Technical Parameters
| Category | Specifications & Technical Details |
| Precision-Matched Cone & Cup Pairing | We pair-grind the inner ring assembly (cone) and outer ring (cup) on the production line to micron-level contact angle and clearance tolerances. This ensures even load distribution after assembly. As a result, it prevents early spalling caused by mixing components from different manufacturers. |
| 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 impact load. Moreover, it greatly improves spalling fatigue life. |
| High-Purity Vacuum-Degassed 100Cr6 Steel | We manufacture the inner and outer rings and rollers from high-purity quenched bearing steel. The surface achieves extremely high hardness and wear resistance, while the core retains good toughness to withstand severe road impact. |
| 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. |
| OEM-Grade Contact Angle & Preload Tolerance | We manufacture strictly to ISO / DIN international standards and provide precisely matched taper angles and clearance tolerances. As a result, the bearing runs smoothly without seizing under high-temperature thermal expansion. |
Applicable Car Brands & Models
Common warning symptoms include:
Deep Roaring or Grinding Noise: A persistent low-pitched rumble from the wheel end or differential that increases in volume with vehicle speed.
Excessive Wheel Hub End-Play: Loose or unstable wheel movement detected when shaking the raised tire at the top and bottom.
Abnormal Hub Temperature: The wheel hub or differential housing becomes excessively hot to the touch after highway operation.
Metal Shavings in Hub Oil/Grease: Metallic glitter or fine flakes recovered during routine hub oil changes or brake service.
Replacing only the cone (inner assembly) while reusing a worn cup (outer ring) causes uneven stress contact across raceway surfaces. Microscopic wear patterns on old cups accelerate roller damage, leading to early noise, overheating, and sudden bearing failure.
Yes. Excessive tightness (over-tightening the spindle nut) generates high thermal friction and crushes raceway surfaces, while excessive looseness causes impact pounding and chatter marks. Technicians must adjust bearing preload using a torque wrench and dial indicator according to manufacturer specs.
Our 1-year warranty covers all raceway spalling, roller fatigue fracture, cage damage, manufacturing dimensional defects, and non-artificial mechanical failures under normal operating conditions. If a set fails within 12 months, we provide prompt replacement or warranty processing upon inspection.
