6213-ZNR Bearing Product Overview & Core Advantages
The 6213-ZNR is a single row deep groove ball bearing designed for robust performance in demanding applications. A key distinguishing feature is its snap ring groove and fitted snap ring on the outer ring, which facilitates secure axial location within a housing, simplifying assembly and enhancing operational reliability. Manufactured from high-grade chrome steel with a stainless steel cage, this bearing offers excellent durability and consistent operation. It is pre-lubricated with grease and features integral shields, making it a low-maintenance solution suitable for a wide temperature range.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6213 | Standard bearing series designation, indicating a single row deep groove ball bearing with a 65mm bore, 120mm OD, and 23mm width. |
| Z | Signifies a shield on one side of the bearing. This provides effective protection against contaminant ingress while generating less friction than contact seals. |
| NR | Indicates the outer ring has a snap ring groove and is supplied with a fitted snap ring. This feature allows for secure axial positioning, eliminating the need for complex housing shoulders or end caps. |
6213-ZNR Bearing Structural Features & Performance Benefits
- Snap Ring Locating Feature: The integrated snap ring groove and supplied snap ring enable simplified and secure mounting. This design enhances axial stability and is ideal for applications where housing design must be compact or where bearing location is critical.
- Shielded & Pre-Lubricated Design: The single-sided shield effectively retains the factory-applied grease lubrication and excludes larger contaminants. This combination results in a maintenance-free bearing for the majority of its service life, reducing total cost of ownership.
- Robust Load Capacity: With a dynamic load rating of 13,151 lbf and a static load rating of 9,105 lbf, this bearing is engineered to handle significant radial loads and moderate axial loads, ensuring long-term operational reliability.
- Precision and Material Integrity: Manufactured to P0 tolerance class with a standard CN radial internal clearance, it offers consistent performance. The use of chrome steel for rings and balls, combined with a stainless steel cage, provides excellent resistance to wear and corrosion.
