6311-ZN Bearing Product Overview & Core Advantages
The 6311-ZN is a single row deep groove ball bearing designed for exceptional performance in demanding industrial applications. Engineered with shielded protection on one side, this bearing effectively prevents the ingress of contaminants while retaining lubrication. Its key advantages include a high radial dynamic load rating of 16,096 lbf, making it suitable for applications with significant radial forces. Manufactured to ABEC 1 | ISO P0 tolerance standards, it ensures reliable and consistent operation. The inclusion of a snap ring groove on the outer ring facilitates secure and simplified axial location within a housing, enhancing mounting efficiency and system stability.
6311-ZN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6311 | Basic bearing designation indicating a single row deep groove ball bearing with a 55mm bore, 120mm OD, and 29mm width. |
| Z | Denotes a shielded (non-contact) side on the bearing. This protects against contaminants from one direction. |
| N | Indicates a snap ring groove on the outer ring for axial location and secure housing fit. |
6311-ZN Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from chrome steel for both rings, balls, and cage, this bearing offers high strength and durability. The deep groove raceway and robust design enable it to handle high radial dynamic and static loads, ensuring long service life under strenuous conditions.
- Contamination Protection: The shielded (Z) design provides a critical defense against dust and debris, making it ideal for environments where contamination is a concern. This helps to extend the bearing's operational life by preserving internal components.
- Simplified Mounting and Axial Location: The outer ring snap ring groove (N) allows for easy and secure axial positioning within the housing. This feature eliminates the need for complex housing shoulders or locknuts, simplifying assembly and reducing total system cost.
- Standard Precision & Clearance: Built to ABEC 1 (ISO P0) tolerance class with a CN radial internal clearance, this bearing provides reliable, smooth running performance suitable for a wide range of general industrial applications.
6311-ZN Bearing Typical Application Areas
The 6311-ZN is versatile and finds use in numerous sectors requiring reliable radial load support and simplified mounting. Key application areas include:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Pumps and Fans
