Description
Maximize radial load capacity and ensure whisper-quiet power transmission across your commercial fleet with the genuine SKF Commercial Vehicle Radial & Double Row Cylindrical Roller Bearing. Engineered specifically for heavy-duty commercial truck gearboxes, final drives, auxiliary power units, and multi-axle wheel drives, this OE-grade cylindrical bearing handles massive radial loads and high rotational speeds with minimal friction. Pitted raceways, spalled steel rollers, cracked synthetic cages, or thermal oil breakdown cause high-pitched transmission whining, excessive shaft runout, lubricant leakage, and sudden gearbox lockup. This original SKF cylindrical roller bearing solves those transmission failures directly. It features premium high-purity 100Cr6 bearing steel, logarithmic roller contact geometry, reinforced brass or polymer cages, and high-precision grinding tolerances 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 cylindrical roller generatrix to a logarithmic curve. This completely eliminates edge stress under heavy-load deflection or impact load. 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-resistant compressive strength, while the core retains good toughness to withstand strong transmission impact. |
| Double-Row High-Capacity Roller Arrangement | We use a double-row cylindrical roller parallel arrangement. It multiplies radial load-bearing area within limited radial space. Therefore, it perfectly meets the high-torque output demands of heavy truck main and auxiliary transmissions. |
| Machined Brass & Polymer Cage Architecture | We equip high-strength solid machined brass or reinforced polymer cages. They precisely guide each roller for smooth running even at high speed and during momentary poor lubrication. Moreover, they prevent seizure. |
| Separable Inner/Outer Ring Configuration | Some models use a separable ribbed inner and outer ring structure. This makes press-fit alignment on the gearbox shaft journal and routine maintenance inspection easier. |
Applicable Car Brands & Models
Common warning symptoms include:
High-Pitched Transmission Whining or Roaring: A persistent mechanical whining noise originating from the gearbox that changes pitch with vehicle speed or gear selection.
Excessive Transmission Shaft Play: Looseness or radial runout detected on gearbox input or output shafts during teardown inspection.
Metal Shavings on Magnetic Drain Plugs: Fine metallic flakes or broken cage fragments recovered during routine transmission oil changes.
Gearbox Overheating: Abnormal high operating temperatures measured on transmission housings caused by internal bearing friction buildup.
Premature failure is typically caused by contaminated gear oil (metal debris or water incursion), inadequate lubrication levels, thermal overload from continuous heavy pulling, or incorrect press-fit installation damaging the raceways.
No. Although cylindrical roller bearings feature separable components for easy installation, you must never mix inner and outer rings from different manufacturing batches or part numbers, as precise internal radial clearances will be compromised.
Our 1-year warranty covers all raceway spalling, roller fatigue fracture, cage structural breakage, manufacturing dimensional flaws, and non-artificial mechanical failures under normal operating and lubrication conditions. If a bearing fails within 12 months, we provide prompt replacement or warranty processing upon inspection.
