Description
Maximize rotational efficiency and minimize frictional power loss across your commercial fleet with the genuine SKF Commercial Vehicle Deep Groove Ball Bearing & Radial Ball Bearing. Engineered specifically for heavy-duty commercial truck alternators, water pumps, cooling fan hubs, auxiliary gearboxes, and multi-axle driveline accessories, this OE-grade radial ball bearing supports simultaneous radial loads and moderate axial forces in both directions under continuous high-speed operation. Pitted raceways, spalled steel balls, degraded rubber seals, or thermal lubricant breakdown cause high-pitched mechanical whining, excessive shaft play, grease leakage, and sudden accessory lockup. This original SKF deep groove ball bearing solves those rotational failures directly. It features premium high-purity 100Cr6 bearing steel, super-finished raceway grooves, reinforced cages, and advanced low-friction contact seals to deliver whisper-quiet operation, ultra-low torque loss, and uncompromised fleet reliability in demanding transport operations.
Technical Parameters
| Category | Specifications & Technical Details |
| High-Purity Vacuum-Degassed 100Cr6 Steel | We manufacture the inner and outer 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 Balls | We micron-level super-finish the raceway surfaces. Consequently, this greatly reduces rolling friction resistance and operating noise. Notably, it meets the low-power consumption requirements of continuous high-speed engine auxiliary drive operation. |
| Optimized Dual-Lip Rubber Sealing Technology | We equip specialty NBR / FKM dual-lip contact rubber seals (2RS). They effectively block dust particles, muddy water, and high-temperature oil mist in the engine bay. Additionally, they prevent internal grease leakage. |
| Pre-Lubricated High-Performance Synthetic Grease | We pre-fill the bearing with long-life synthetic grease. It withstands extreme operating temperatures from -40°C to 150°C. Moreover, it offers excellent resistance to oxidative breakdown and water washout. |
| OEM-Grade Precision Tolerance & Internal Clearance | We produce strictly to ISO / DIN international standards and offer C3 precision internal clearance. As a result, the bearing runs smoothly without seizing under engine high-temperature thermal expansion. |
Applicable Car Brands & Models
Common warning symptoms include:
High-Pitched Whining or Humming Noise: Excessive noise originating from engine accessory pulleys or auxiliary gearboxes that increases in pitch with engine RPM.
Excessive Shaft Play or Wobble: Noticeable radial looseness in belt tensioners, alternator shafts, or water pump pulleys during manual inspection.
Overheating Around Bearing Housing: High operating temperatures detected on accessory brackets caused by friction buildup inside worn raceways.
Grease Leakage or Discolored Residue: Darkened grease or brown dust leaking past damaged rubber seal lips onto surrounding components.
Premature failure is typically caused by excessive belt tension overloading the radial load, improper installation using incorrect press tools, thermal overload from cooling system failure, or abrasive dust contamination penetrating compromised seals.
Yes. Sealed SKF 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.
