13948 Bearing Product Overview & Core Advantages
The 13948 is a double row angular contact ball bearing designed for demanding industrial applications requiring high load capacity and rigidity. This precision bearing is engineered to accommodate combined loads—simultaneous radial and axial forces—making it an ideal solution for complex load scenarios. Its open design, pre-lubricated for immediate service, ensures reliable performance in a wide operating temperature range. With its robust construction and high dynamic load rating, the 13948 delivers exceptional durability and operational stability.
13948 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 13948 | Basic bearing designation number. |
| Open (from specs) | No contact seals or shields, allowing for higher speeds and facilitating re-lubrication. |
| Lubricated (from specs) | Factory-filled with high-performance grease for immediate operation. |
| Annular Groove & Holes | Features an outer ring lubrication groove (8.3mm) and holes (4.5mm diameter) for efficient re-lubrication during service. |
13948 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and optimized internal geometry provide superior stiffness, enabling the bearing to handle significant radial dynamic loads (13,612 lbf) and static loads (6,862 lbf) with minimal deflection.
- Optimized for Combined Loads: The angular contact design is inherently suited for applications involving combined radial and axial loads, ensuring stable operation under complex force conditions.
- Enhanced Service Life & Re-lubrication: The stainless steel cage ensures low wear and high corrosion resistance. The presence of lubrication features on the outer ring allows for periodic re-lubrication, significantly extending the bearing's operational life in demanding environments.
- Precision Dimensions: Manufactured to tight dimensional tolerances on the bore diameter (240 mm), outside diameter (320 mm), and width (60 mm), guaranteeing precise fit and consistent performance in high-precision assemblies.
13948 Bearing Typical Application Areas
The 13948 double row ball bearing is ideally suited for heavy-duty machinery and equipment where high load capacity and rigidity are paramount. Common applications include:
- Industrial Gearboxes and power transmission systems
- Large Pumps and compressors
- Material Handling Equipment such as conveyor pulleys
- Construction and Mining Machinery
- Heavy-duty industrial fans and blowers
