215-ZNR Bearing Product Overview & Core Advantages
The 215-ZNR is a single row deep groove ball bearing engineered for high performance in demanding applications. This metric bearing is distinguished by its shielded design and integrated snap ring, offering reliable radial load capacity and simplified axial positioning. Manufactured with chrome steel rings and balls, and a stainless steel cage, it delivers exceptional durability and consistent operation. Pre-lubricated with grease, it provides a long service life and is suitable for a wide temperature range from -30°C to 120°C. Its compact design and P0 tolerance class make it an ideal choice for applications requiring precision and reliability.
215-ZNR Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 215 | Standard bearing series designation, indicating the core dimensions (75mm bore, 130mm OD, 25mm width). |
| Z | Signifies a shielded bearing on one side, providing protection against contaminants. |
| NR | Indicates the outer ring is equipped with a snap ring (fitted), facilitating secure axial location within a housing. |
215-ZNR Bearing Structural Features & Performance Benefits
- Robust Load Capacity: The single row deep groove construction is optimized to handle significant radial loads (Dynamic: 16,209 lbf, Static: 16,186 lbf), ensuring stable performance under stress.
- Simplified Assembly and Positioning: The integrated snap ring on the outer ring eliminates the need for complex housing shoulders or end caps, reducing assembly time and cost while providing secure axial location.
- Contamination Protection: The shielded (Z) design effectively seals the bearing, protecting the grease lubrication and internal components from dust and debris, enhancing operational reliability.
- High-Speed Capability: The combination of a stainless steel cage and optimized grease lubrication allows for a high limiting speed of 5,300 rpm, suitable for a wide range of industrial speeds.
- Precision and Consistency: Manufactured to P0 tolerance class with a standard CN radial internal clearance, this bearing offers predictable performance and smooth operation in general applications.
