313-2Z Bearing Product Overview & Core Advantages
The 313-2Z is a single row deep groove ball bearing designed for exceptional performance in demanding applications. Engineered with precision and reliability, this bearing excels at handling primarily radial loads and moderate axial loads in both directions. Its shielded construction provides effective contamination protection, while the pre-lubrication ensures long service life and reduced maintenance. The combination of high load capacity and a robust design makes it an ideal choice for applications requiring high rigidity and dependable operation.
313-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 313 | Standard bearing series designation indicating specific bearing dimensions (65mm bore, 140mm OD, 33mm width). | Defines the physical size and load-carrying capacity. |
| -2Z | Signifies the bearing is equipped with non-contact shields on both sides. | Offers effective protection against dust and contaminants while maintaining high-speed capability. |
313-2Z Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row deep groove raceway and robust chrome steel construction provide excellent radial dynamic load rating (22,931 lbf) and static load rating (20,233 lbf), ensuring stable performance under significant stress.
- Optimized High-Speed Performance: The lightweight nylon cage minimizes centrifugal forces and friction, contributing to a high limiting speed of 4,300 rpm. The non-contact shields further reduce drag, enabling efficient operation.
- Low Maintenance & Longevity: The combination of pre-lubricated grease and effective sealing from the 2Z shields creates a sealed-for-life unit, reducing the need for re-lubrication and extending service intervals.
- Precision Engineering: Manufactured to P0 tolerance class and standard CN radial internal clearance, this bearing delivers consistent and reliable performance for a wide range of industrial applications.
313-2Z Bearing Typical Application Areas
This versatile ball bearing is widely used across various industries due to its robust design and reliable performance. Key application areas include:
- Electric Motors and Generators
- Industrial Gearboxes
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Pumps and Compressors
- General Industrial Machinery requiring dependable radial load support.
