6412 NR Bearing Product Overview & Core Advantages
The 6412 NR is a single row deep groove ball bearing engineered for high-performance applications requiring robust radial load capacity and reliable operation. Its defining feature is the integral snap ring on the outer ring, which facilitates secure axial location within a housing, simplifying assembly and reducing the need for complex housing designs. Manufactured with chrome steel rings and balls, and a stainless steel cage, this bearing offers excellent durability and is supplied in the standard P0 tolerance class with CN radial internal clearance, making it a versatile and cost-effective solution for a wide range of industrial machinery.
Model Code Breakdown
| Code Segment | Interpretation | Technical Significance |
|---|---|---|
| 6412 | Basic Bearing Number | Indicates a metric, single row deep groove ball bearing with a 60 mm bore, 150 mm OD, and 35 mm width. |
| NR | Snap Ring Groove | Specifies that the bearing outer ring has a groove and is supplied with a fitted snap ring for axial location. |
6412 NR Bearing Structural Features & Performance Benefits
- Snap Ring for Simplified Assembly: The integrated snap ring (159.7 mm OD, 2.82 mm width) acts as a positive outer ring locating feature, allowing for a simpler, more compact housing design by eliminating the need for shoulders, end covers, or complex clamping mechanisms. This significantly reduces assembly time and cost.
- High Load Capacity: With a dynamic load rating of 24,279 lbf and a static load rating of 15,624 lbf, this bearing is built to handle significant radial loads in demanding applications.
- Robust Construction: The combination of chrome steel rings and balls provides high wear resistance and fatigue life. The stainless steel cage ensures cage integrity and reliable performance under high-speed conditions, contributing to a limiting speed of 6,300 rpm.
- Standardized Precision: The P0 tolerance class and CN radial clearance offer a balance of performance and value, suitable for the vast majority of general industrial applications.
6412 NR Bearing Typical Application Areas
The 6412 NR is ideally suited for applications where secure axial location and high radial load capacity are paramount. Common uses include:
- Electric Motors and Gearboxes
- Industrial Fans and Blowers
- Material Handling Conveyors
- Agricultural Machinery
- Pumps and Compressors
