216 NR/C3 Bearing Product Overview & Core Advantages
The 216 NR/C3 is a single row deep groove ball bearing engineered for robust radial load capacity and reliable performance in demanding industrial applications. This metric bearing features a unique snap ring on its outer ring, enabling secure axial location within a housing without requiring complex machining. Manufactured to ABEC 1 | ISO P0 tolerance standards with a C3 radial internal clearance, it is designed to accommodate thermal expansion in applications with elevated operating temperatures. Its open design allows for versatile lubrication options, making it an excellent choice for high-performance machinery requiring dependable radial load support.
216 NR/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 216 | Standard bore diameter code (80 mm) |
| NR | Snap Ring groove and fitted snap ring on the outer ring for secure axial location. |
| C3 | Greater than normal radial internal clearance, suitable for applications with significant temperature gradients or interference fits. |
216 NR/C3 Bearing Structural Features & Performance Benefits
- Snap Ring Design: The integrated snap ring (located on a 149.7 mm outside diameter) simplifies housing design and assembly, providing a cost-effective method for axial retention and enhancing operational reliability.
- High Load Capacity: Constructed from chrome steel for both rings, balls, and cage, this bearing delivers a high radial dynamic load rating of 19,783 lbf and a static load rating of 19,109 lbf, ensuring durability under heavy loads.
- Optimized Internal Clearance: The C3 clearance allows for thermal expansion, preventing premature failure in applications where operating temperatures cause dimensional changes in the bearing and surrounding components.
- Standard Precision & Versatility: As an open bearing with ABEC 1 (ISO P0) precision, it offers flexibility for custom lubrication regimes to suit specific speed and temperature requirements, with a limiting speed of 5,000 rpm.
