312NR Bearing Product Overview & Core Advantages
The 312NR is a single row deep groove ball bearing designed for high performance and reliability in industrial applications. Its core advantage lies in its ability to efficiently handle radial loads while offering a robust and compact design. A key feature is the snap ring fitted on the outer ring, which simplifies axial location within a housing, reducing assembly complexity and cost. Manufactured to ABEC 1 | ISO P0 tolerance standards, it ensures consistent and precise operation, making it an excellent choice for general machinery requiring dependable performance.
312NR Bearing Model Code Explained, Specifications & Naming Convention
| 312 | Standard bore diameter code and series designation. |
| NR | Indicates the bearing has a snap ring groove and a snap ring fitted on its outer ring. This feature aids in axial positioning. |
Note: The absence of seals (Open type) and specific lubrication suffixes indicates this is an open bearing supplied without grease, intended for applications where a specific lubricant will be applied by the user.
312NR Bearing Structural Features & Performance Benefits
- Snap Ring Locating Feature: The integrated snap ring on the outer ring provides a simple and effective method for axial location, preventing creep and simplifying housing design. This contributes to the bearing's ease of assembly and high rigidity in the installed state.
- Robust Load Capacity: With a dynamic load rating of 20,525 lbf and a static load rating of 17,535 lbf, this bearing is engineered to handle significant radial loads in demanding environments.
- Precision & Consistency: Manufactured to ABEC 1 | ISO P0 tolerance class with a standard CN radial internal clearance, it delivers reliable and predictable performance, ensuring smooth operation and reduced vibration.
- High-Quality Material Construction: All critical components, including rings, balls, and cage, are made from chrome steel, providing excellent durability, wear resistance, and a long operational lifespan.
