313-ZNR Bearing Product Overview & Core Advantages
The 313-ZNR is a single row deep groove ball bearing designed for exceptional radial load capacity and reliable performance in demanding applications. Its shielded construction provides effective contaminant protection while maintaining low friction operation. A key feature is the integral snap ring on the outer ring, which simplifies axial positioning and reduces housing design complexity. Manufactured with precision tolerances (P0 class) and pre-lubricated with grease, this bearing offers a robust solution for applications requiring high rigidity and consistent operation.
313-ZNR Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| 313 | Standard bearing series designation | Defines basic bearing dimensions (65mm bore × 140mm OD × 33mm width) |
| Z | One side shielded | Protects against contaminants while allowing high-speed operation |
| NR | Snap ring groove with snap ring | Enables simplified axial positioning and reduces assembly costs |
313-ZNR Bearing Structural Features & Performance Benefits
Optimized Load Distribution: The single row deep groove raceway design enables excellent radial load capacity (22,931 lbf dynamic rating) while accommodating moderate axial loads in both directions. The stainless steel cage ensures reliable ball guidance and contributes to smooth operation at limiting speeds up to 5,300 rpm.
Enhanced Sealing & Lubrication: The shielded construction provides effective protection against contamination while maintaining low operating torque. Pre-lubricated with high-quality grease, the bearing operates reliably across a wide temperature range from -30°C to 120°C, reducing maintenance requirements.
Precision Engineering: Manufactured to P0 tolerance class with CN radial clearance, this bearing delivers consistent performance and long service life. The chrome steel rings and balls provide excellent wear resistance and durability under demanding conditions.
313-ZNR Bearing Typical Application Areas
- Electric Motors and industrial drives requiring reliable radial support
- Gearboxes and transmission systems where precise shaft positioning is critical
- Material Handling Equipment such as conveyor systems and pulleys
- Agricultural Machinery requiring robust bearing solutions with simplified mounting
- Industrial Pumps and compressors operating at moderate to high speeds
- Automotive Components where snap ring mounting simplifies assembly processes
