6313-ZNR (CN) Bearing Product Overview & Core Advantages
The 6313-ZNR (CN) is a single row deep groove ball bearing engineered for exceptional performance in demanding applications. This precision bearing is distinguished by its shielded design and a snap ring groove on its outer ring, facilitating secure axial location within a housing. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers reliable operation and high rotational accuracy. Its robust construction from chrome steel ensures durability and a long service life, making it an ideal solution for applications requiring dependable radial load capacity and simplified assembly.
6313-ZNR (CN) Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| ZNR | This is a combined suffix. Z indicates a steel shield on one side. NR indicates a snap ring groove and a snap ring is fitted on the outer ring. | The shield provides effective contaminant protection, while the snap ring simplifies axial positioning, reducing assembly time and cost. |
| (CN) | Specifies the radial internal clearance group, which is C0 (Normal clearance). | Ensures optimal performance under standard operating conditions and temperatures. |
6313-ZNR (CN) Bearing Structural Features & Performance Benefits
- Shielded Design: The integral steel shield (Z-type) effectively retains lubrication and excludes larger contaminants like dust and debris, enhancing bearing life without significantly increasing friction.
- Snap Ring Groove & Fitted Snap Ring: This feature allows for secure axial location of the bearing within a simple, un-machined housing bore, offering a cost-effective mounting solution and simplifying overall assembly design.
- High Load Capacity: The deep groove raceway and robust construction enable the bearing to support significant radial dynamic load ratings (2084 lbf) and radial static load ratings (13466 lbf).
- Precision Performance: Manufactured to ABEC 1 | ISO P0 tolerance class, this bearing ensures smooth, quiet, and reliable operation with minimal runout.
- Material Integrity: Components made from high-carbon chrome steel (GCr15) provide high hardness, wear resistance, and dimensional stability under load.
