6012 NR/C4 Bearing Product Overview & Core Advantages
The 6012 NR/C4 is a single row deep groove ball bearing designed for robust performance in demanding industrial applications. This open-type bearing is engineered to primarily handle radial loads with high efficiency. A key structural feature is the integral snap ring on the outer ring, which provides secure axial location within a housing, simplifying assembly and reducing the need for complex housing designs. Manufactured to ABEC 1 | ISO P0 tolerance standards and featuring a C4 radial internal clearance, this bearing is optimized for applications with potential thermal expansion, ensuring reliable operation and high rigidity.
6012 NR/C4 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6012 | Standard bearing series designation indicating a metric, single row deep groove ball bearing with a 60mm bore and 95mm outside diameter. | Defines the core bearing dimensions and type. |
| NR | Outer ring has a snap ring groove and a snap ring is fitted. | Enables secure axial location, simplifies housing design, and reduces assembly costs. |
| C4 | Radial internal clearance greater than Normal (C0) group. | Accommodates thermal expansion in applications with high operating temperatures or where fits result in a reduction of internal clearance. |
6012 NR/C4 Bearing Structural Features & Performance Benefits
- Snap Ring Locating Feature: The fitted snap ring on the outer ring provides a positive axial location, enhancing operational stability and simplifying the surrounding housing structure. This contributes to the overall high rigidity of the assembly.
- Optimized Internal Clearance: The C4 radial clearance is a critical performance feature. It prevents pre-loading and potential seizure in applications prone to thermal expansion, ensuring smooth running and a long service life.
- Open Design & High-Speed Capability: As an open bearing without integral seals, it is suitable for high-speed operation (limiting speed of 9,500 rpm), allowing for efficient airflow and heat dissipation. This design is ideal for systems with centralized lubrication.
- Robust Load Capacity: With a dynamic load rating of 6,902 lbf and a static load rating of 5,216 lbf, this bearing is built to handle significant radial loads reliably.
6012 NR/C4 Bearing Typical Application Areas
The 6012 NR/C4 is well-suited for a variety of industrial machinery and equipment where secure location and accommodation for thermal expansion are required. Common applications include:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Conveyors
- Agricultural Machinery
- General Industrial Machinery requiring a cost-effective locating solution
