314-ZNR Bearing Product Overview & Core Advantages
The 314-ZNR is a single row deep groove ball bearing engineered for high-performance industrial applications. This shielded bearing excels in handling substantial radial loads while offering reliable operation. A key distinguishing feature is its snap ring on the outer ring, which simplifies axial location and mounting within a housing. Manufactured to P0 tolerance class with standard CN radial internal clearance, it provides a robust and cost-effective solution for a wide range of machinery requiring precision and durability.
314-ZNR Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 314 | Basic bearing designation indicating the size series and bore diameter (70 mm). |
| Z | Denotes a shielded bearing on one side, protecting the internal components from large particulate contaminants. |
| NR | Indicates the outer ring has a snap ring groove and is supplied with a snap ring. This feature aids in axial location, reducing the need for complex housing shoulders and simplifying assembly. |
314-ZNR Bearing Structural Features & Performance Benefits
- Simplified Mounting and Axial Location: The integrated snap ring (fitted) allows for secure axial positioning within the housing, eliminating the need for complex machining and reducing assembly time and cost.
- Robust Contamination Protection: The shielded design effectively prevents the ingress of large solid contaminants, enhancing bearing service life in challenging environments.
- High Load Capacity: Constructed from chrome steel rings and balls, this bearing offers a high dynamic load rating of 25,628 lbf and a static load rating of 22,931 lbf, ensuring reliable performance under significant radial loads.
- Ready-to-Use Lubrication: Pre-lubricated with grease, the bearing is ready for immediate installation, supporting a broad operating temperature range from -30°C to 120°C.
- Stable Cage Design: The stainless steel cage provides excellent guidance for the balls, contributing to smooth operation and stable performance at the specified limiting speed.
314-ZNR Bearing Typical Application Areas
This versatile bearing is ideally suited for applications requiring reliable radial load support and simplified mounting. Key industries and equipment include:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Fans and Blowers
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
