6313 NRJEM Bearing Product Overview & Core Advantages
The 6313 NRJEM is a single row deep groove ball bearing engineered for exceptional radial load capacity and reliable performance in a wide range of industrial applications. Its open design allows for versatile lubrication options, while the integrated snap ring on the outer ring provides secure axial location within a housing, simplifying assembly and enhancing operational stability. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing offers a robust and cost-effective solution for general machinery requiring dependable support and moderate speed operation.
Model Code Breakdown
| Model Segment | Interpretation | Technical Significance |
|---|---|---|
| 6313 | Basic Bearing Number | Defines the standard metric dimensions: 65mm bore, 140mm OD, 33mm width. |
| NR | Snap Ring Groove & Ring | Specifies that the outer ring has a groove and is supplied with a snap ring for axial location. |
| JEM | Steel Cage Design & Clearance | Indicates a pressed steel cage and CN group radial internal clearance (normal clearance). |
6313 NRJEM Bearing Structural Features & Performance Benefits
Optimized for Radial Loads: The single row deep groove construction is primarily designed to support high radial dynamic load ratings (21,919 lbf), making it ideal for applications where radial forces are dominant.
Secure Axial Location: The inclusion of a snap ring fitted to the outer ring groove prevents creeping and simplifies housing design by eliminating the need for complex shoulders, ensuring stable bearing positioning.
Robust Construction & Material Integrity: Manufactured entirely from chrome steel for rings, balls, and cage, this bearing ensures high strength, durability, and consistent performance under standard operating temperatures (-30°C to 120°C).
Standardized Precision & Versatility: Conforming to ABEC 1 (ISO P0) tolerance class and CN clearance, it provides reliable, standardized performance for a vast majority of industrial applications without the cost of ultra-high precision.
6313 NRJEM Bearing Typical Application Areas
