6313-2RS1/C3 GJN Bearing Product Overview & Core Advantages
The 6313-2RS1/C3 GJN is a sealed deep groove ball bearing designed for robust performance in demanding applications. As a metric single row bearing, it excels at handling high radial loads while accommodating moderate axial loads in both directions. Its key advantages include the integrated 2RS1 rubber seals for effective contamination exclusion, a C3 radial internal clearance suitable for applications with thermal expansion, and the GJN designation indicating a polyurea grease fill optimized for a wide operating temperature range. This combination delivers long service life and reliable operation with minimal maintenance.
6313-2RS1/C3 GJN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6313 | Basic bearing series; 65mm bore, 140mm OD, 33mm width | Standardized dimensions for easy interchangeability |
| 2RS1 | Contact rubber seals on both sides | Superior protection against contaminants and moisture retention |
| C3 | Greater than normal radial internal clearance | Accommodates shaft expansion in high-temperature or high-speed applications |
| GJN | Polyurea grease filling | Extended lubrication life, stable performance from -30°C to 120°C |
6313-2RS1/C3 GJN Bearing Structural Features & Performance Benefits
Robust Construction: Manufactured entirely from chrome steel for rings, balls, and cage, this bearing ensures high strength and durability under substantial radial dynamic load ratings.
Enhanced Sealing: The 2RS1 contact seals provide an effective barrier against dust, dirt, and other contaminants, significantly extending bearing life in harsh environments. This makes the unit effectively pre-lubricated and sealed for life.
Optimized Internal Clearance: The C3 clearance is a critical feature for applications where thermal expansion of the shaft or housing is expected, preventing preload and potential seizure, thereby ensuring smooth operation.
High-Speed Capability: With a limiting speed of 4,800 rpm, it is suitable for a wide range of industrial machinery requiring reliable performance at moderate to high rotational speeds.
