213NR/C3 Bearing Product Overview & Core Advantages
The 213NR/C3 is a single row deep groove ball bearing engineered for high-performance industrial applications requiring robust radial load capacity and reliable operation. Its defining feature is the integrated snap ring on the outer ring, which simplifies axial location and housing design, saving space and assembly time. Manufactured to ABEC 1 | ISO P0 tolerance standards and featuring a C3 radial internal clearance, this bearing is optimized for applications with anticipated thermal expansion or where interference fits are used, ensuring consistent performance under varying operational conditions.
Model Code Breakdown
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 213 | Basic bearing series and size designation. | Defines the standard bearing dimensions (65mm bore, 120mm OD, 23mm width). |
| NR | Outer ring with a snap ring groove and a snap ring fitted. | Enables secure axial location within the housing without additional components, simplifying design and assembly. |
| C3 | Radial internal clearance greater than the Normal (C0) group. | Accommodates thermal expansion from high speeds or interference fits, preventing premature failure due to excessive preload. |
213NR/C3 Bearing Structural Features & Performance Benefits
- Snap Ring Design: The fitted snap ring on the outer ring provides a positive axial locating feature. This eliminates the need for complex housing shoulders or end caps, leading to a more compact and cost-effective overall design.
- Robust Load Capacity: The single row deep groove construction is optimized to handle significant radial loads (13,601 lbf dynamic, 13,151 lbf static) and moderate axial loads in both directions, making it a versatile choice for various drive systems.
- Precision & Reliability: Manufactured from high-grade chrome steel for both rings, balls, and cage, and conforming to ABEC 1 | ISO P0 precision class, this bearing ensures smooth, low-vibration, and reliable operation.
- Operational Flexibility: The open (unsealed) design allows for the application of specialized lubricants suited to specific operational environments. With a limiting speed of 6,000 rpm and a wide operating temperature range (-30°C to 120°C), it is suitable for demanding applications.
213NR/C3 Bearing Typical Application Areas
This bearing is ideally suited for applications where secure axial location and high radial load capacity are paramount. Key industries and equipment include:
- Electric Motors and Gearboxes: For shaft location and supporting radial loads.
- Industrial Pumps and Compressors: Where the snap ring simplifies housing design.
- Agricultural and Construction Machinery: In drivelines and implement wheels requiring robust performance.
- Material Handling Equipment: Conveyor rollers and pulley systems.
