6212-2RS1NR Bearing Product Overview & Core Advantages
The 6212-2RS1NR is a single row deep groove ball bearing designed for reliable performance in a wide range of industrial applications. Its key advantages stem from its sealed design and integrated snap ring. The 2RS1 designation indicates contact seals on both sides, providing excellent protection against contaminants and retaining lubricant for extended service life. The snap ring (NR) on the outer ring simplifies axial location within a housing, reducing design complexity and assembly time. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing offers a robust and cost-effective solution for applications requiring dependable radial load capacity and moderate speeds.
6212-2RS1NR Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6212 | Basic model number indicating a single row deep groove ball bearing with a 60 mm bore, 110 mm OD, and 22 mm width. | Standardized dimensions for easy interchangeability and selection. |
| 2RS1 | Designates contact seals made from NBR (Nitrile Rubber) on both sides of the bearing. | Provides superior protection against dust, moisture, and other contaminants. Retains lubricant, promoting a maintenance-free operation. |
| NR | Indicates a snap ring groove and a fitted snap ring on the outer ring. | Facilitates easy axial location and secure mounting in a housing, eliminating the need for complex housing shoulders or locknuts. |
6212-2RS1NR Bearing Structural Features & Performance Benefits
- Sealed & Protected Design: The NBR contact seals (2RS1) effectively shield the internal components from contaminants, making the bearing ideal for dirty or humid environments. This design significantly extends the bearing's operational life by preventing premature failure.
- Simplified Mounting with Snap Ring: The outer ring is equipped with a snap ring (NR), which acts as a positive axial locating feature. This simplifies the housing design, reduces machining costs, and ensures secure axial positioning without additional components.
- Robust Load Capacity: Constructed entirely from chrome steel, including the rings, balls, and cage, this bearing offers a high radial dynamic load rating of 1178 lbf and a radial static load rating of 8138 lbf, providing reliable performance under significant radial loads.
- Standard Precision & Clearance: Manufactured to ABEC 1 (ISO P0) tolerance class with a standard CN radial internal clearance, this bearing ensures consistent, smooth running and is suitable for a vast majority of general industrial applications.
6212-2RS1NR Bearing Typical Application Areas
