6313-Z Bearing Product Overview & Core Advantages
The 6313-Z is a single row deep groove ball bearing designed for exceptional performance in demanding applications. Engineered with metric dimensions and manufactured to P6 tolerance class, this bearing offers high precision and reliable operation. Its core strength lies in its ability to handle high radial loads efficiently, making it an ideal choice for applications requiring robust support and smooth rotation. The inclusion of a shielded (Z-type) design on one side provides effective protection against contaminant ingress while retaining lubrication, contributing to extended service life and reduced maintenance needs.
6313-Z Bearing Model Code Explained, Specifications & Naming Convention
| Prefix/Suffix | Interpretation | Technical Significance |
|---|---|---|
| 6313 | Basic Bearing Number | Denotes a single row deep groove ball bearing with a 65mm bore, 140mm OD, and 33mm width. |
| -Z | Shield Designation | Indicates a steel shield is fitted on one side of the bearing. This provides protection from large particulate contaminants and helps retain the pre-applied grease lubrication. |
6313-Z Bearing Structural Features & Performance Benefits
- Robust Load Capacity: Manufactured from chrome steel rings and balls, the 6313-Z offers a high radial dynamic load rating of 21,919 lbf and a radial static load rating of 13,489 lbf, ensuring dependable performance under significant stress.
- Precision & High-Speed Operation: Built to a P6 tolerance class for superior dimensional accuracy and running precision. Combined with a lightweight stainless steel cage, it facilitates smooth operation and supports a limiting speed of 6,700 rpm.
- Contamination Resistance & Lubrication: The Z-shield effectively protects the internal components from dust and debris. The bearing is pre-lubricated with grease, providing immediate readiness for installation and operation within a temperature range of -30°C to 120°C.
- Standard Internal Clearance: Features a CN group radial internal clearance, which is the standard and most common clearance, suitable for a wide range of general applications and operating conditions.
