1303G14 Bearing Product Overview & Core Advantages
The 1303G14 is a double row angular contact ball bearing designed for applications requiring high rigidity and reliable performance under combined loads. This precision bearing efficiently handles significant radial loads and moderate axial loads in both directions, thanks to its optimized contact angle and double row design. Its compact construction with a 14 mm width makes it ideal for space-constrained, high-precision assemblies where high rigidity and operational stability are critical. Manufactured with chrome steel components and featuring a nylon cage, it delivers smooth operation at limiting speeds up to 20,000 rpm.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 1303 | Standard bearing series designation indicating bearing dimensions: 17 mm bore, 47 mm OD, 14 mm width. |
| G | Indicates the radial internal clearance group is CN (Normal clearance). |
| 14 | Specifies the bore diameter of 17 mm according to standard inch-to-metric coding. |
1303G14 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball complement and optimized raceway geometry provide superior stiffness, enabling the bearing to withstand substantial combined loads (radial and bidirectional axial) without significant deformation.
High-Speed Performance: The lightweight nylon cage ensures stable ball guidance and reduces centrifugal forces, contributing to the high limiting speed of 20,000 rpm. This makes it suitable for high-speed applications.
Precision & Reliability: Manufactured from high-grade chrome steel with tight dimensional tolerances (bore: -0.008mm to 0), this bearing guarantees precise running accuracy and long-term operational reliability.
Standard Lubrication & Versatility: The bearing comes lubricated and is capable of operating within a broad temperature range of -30°C to 110°C, ensuring performance across various environmental conditions.
1303G14 Bearing Typical Application Areas
- Electric Motors & Generators: For spindle and rotor support where high speeds and radial loads are present.
- Precision Gearboxes: Providing rigid and accurate shaft positioning in industrial transmission systems.
- Pumps & Compressors: Handling combined loads in fluid movement and air compression equipment.
- Material Handling Equipment: Such as conveyor rollers, where reliable bearing performance under radial stress is essential.
- Industrial Fans & Blowers: Supporting shafts in high-speed air movement applications.
