313-Z Bearing Product Overview & Core Advantages
The 313-Z is a single row deep groove ball bearing engineered for superior performance in demanding applications. Its core advantages stem from a design optimized for high radial load capacity and reliable operation. The bearing features integral shielded seals for effective contamination protection and is pre-lubricated with grease, ensuring long service life and minimal maintenance. Manufactured to P0 tolerance class with a standard CN radial internal clearance, it offers a robust and cost-effective solution for a wide range of industrial machinery, providing excellent rotational accuracy and durability.
313-Z Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Code | Technical Meaning |
|---|---|---|
| Basic Designation | 313 | Indicates a single row deep groove ball bearing with a 65mm bore, 140mm OD, and 33mm width. |
| Suffix | Z | Denotes a shielded seal on one side of the bearing. This provides effective protection against solid contaminants while maintaining low friction and allowing for higher limiting speeds compared to contact seals. |
313-Z Bearing Structural Features & Performance Benefits
- High Load Capacity: The optimized deep groove raceway and robust construction enable the bearing to support significant radial dynamic load ratings of 22,931 lbf and radial static load ratings of 20,233 lbf, making it suitable for applications with substantial mechanical stress.
- Shielded Protection: The Z-shield effectively retains lubricant and excludes larger particulate contaminants, enhancing bearing life and reliability in moderately dirty environments.
- Pre-lubricated & Ready-to-Use: Factory-filled grease lubrication simplifies installation and provides immediate, maintenance-free operation for a significant portion of the bearing's service life within its specified temperature range of -30°C to 120°C.
- High-Speed Capability: The combination of a low-friction nylon cage, shielded design, and optimized internal geometry allows for a high limiting speed of 5,300 rpm, catering to applications requiring rapid rotation.
- Material Integrity: Constructed from high-grade chrome steel for both rings and balls, the bearing ensures high strength, wear resistance, and consistent performance under load.
