6310-2Z/HC5C3GJN Bearing Product Overview & Core Advantages
The 6310-2Z/HC5C3GJN is a single row deep groove ball bearing engineered for exceptional performance in demanding applications. This precision bearing is distinguished by its hybrid ceramic construction, featuring Silicon Nitride (Si3N4) balls and chrome steel rings. Its core advantages include the ability to handle high radial loads, operate at elevated speeds, and function with minimal lubrication due to the properties of the ceramic balls. The inclusion of shields (2Z) provides effective contamination protection, making it a robust and reliable choice for high-reliability scenarios.
6310-2Z/HC5C3GJN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6310 | Standard bearing series designation, indicating a metric single row deep groove ball bearing with a 50mm bore, 110mm OD, and 27mm width. |
| 2Z | Bearing is equipped with shields on both sides. This provides protection against solid contaminants while allowing for higher speed capability compared to contact seals. |
| HC5 | Indicates a Hybrid Ceramic construction, specifically with Silicon Nitride (Si3N4) balls. |
| C3 | Specifies a greater than normal radial internal clearance. This is suitable for applications with significant thermal expansion or where interference fits are used. |
| GJN | Indicates the bearing is supplied without lubrication ("None"). |
6310-2Z/HC5C3GJN Bearing Structural Features & Performance Benefits
Hybrid Ceramic Design: The combination of steel rings and Silicon Nitride balls provides significant performance enhancements. Ceramic balls are lighter, harder, and have a lower coefficient of thermal expansion than steel, contributing to higher speed capability, reduced operating temperature, and extended service life.
Contamination Protection: The non-contact shields (2Z) on both sides effectively protect the bearing interior from large particulate contaminants, enhancing reliability in challenging environments without the friction and speed limitations of contact seals.
High Load Capacity: The deep groove raceway and robust construction enable the bearing to support high radial dynamic load ratings (13,938 lbf), making it suitable for applications with significant radial forces.
Precision & Stability: Manufactured to ABEC 1 | ISO P0 tolerance class, this bearing ensures consistent running accuracy and smooth operation, which is critical for maintaining system performance.
6310-2Z/HC5C3GJN Bearing Typical Application Areas
The 6310-2Z/HC5C3GJN is ideally suited for applications requiring high speed, high reliability, and minimal lubrication. Key industries and equipment include:
- Electric Motors & Spindles: Where high rotational speeds and long life are paramount.
- Pumps & Compressors: For handling radial loads in demanding fluid handling systems.
- Precision Machinery: Including machine tools and automation equipment where running accuracy is critical.
- Aerospace & Defense Systems: Applications benefiting from the hybrid ceramic's performance in extreme conditions.
