6319-2RS1/C3 Bearing Product Overview & Core Advantages
The 6319-2RS1/C3 is a single row deep groove ball bearing designed for robust performance in demanding applications. Engineered to primarily handle radial loads, its sealed construction ensures long-term reliability and protection against contamination. A key feature is its C3 radial internal clearance, which accommodates thermal expansion, making it suitable for applications with elevated operating temperatures or where interference fits are used. This bearing offers an excellent balance of high load capacity, operational stability, and maintenance-free service due to its integrated seals and pre-lubrication.
6319-2RS1/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6319 | Basic Bearing Number | Denotes a standard single row deep groove ball bearing with a 95mm bore, 200mm OD, and 45mm width. |
| 2RS1 | Contact Seals on Both Sides | Features nitrile rubber (NBR) seals that make firm contact with the inner ring, providing superior protection against contaminants and moisture retention of lubricant. |
| C3 | Radial Internal Clearance | Indicates a clearance greater than the Normal (CN) group. This is optimal for applications with thermal expansion or heavy interference fits, preventing premature failure due to excessive preload. |
6319-2RS1/C3 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from chrome steel for rings, balls, and cage, this bearing delivers high strength and durability. With a dynamic load rating of 34,396 lbf and a static load rating of 26,752 lbf, it is built to withstand significant radial stresses.
- Sealed for Life & Maintenance-Free Operation: The 2RS1 contact seals effectively shield the internal components from dust, dirt, and other contaminants. This sealed design, combined with factory-applied grease, eliminates the need for re-lubrication, reducing maintenance costs and downtime.
- Thermal Stability with C3 Clearance: The C3 radial internal clearance is a critical feature for applications where bearing temperatures rise during operation. It prevents thermal seizure by allowing for expansion, ensuring consistent performance and extended bearing service life.
- Precision for Reliable Operation: Manufactured to ABEC 1 | ISO P0 tolerance class, this bearing provides the dimensional accuracy and running precision required for smooth and reliable operation in industrial machinery.
