6314-ZNR Bearing Product Overview & Core Advantages
The 6314-ZNR is a single row deep groove ball bearing engineered for exceptional reliability in demanding applications. This shielded bearing features an integral snap ring on its outer ring, enabling simplified axial location within a housing without the need for complex machining. Manufactured from high-grade chrome steel with a stainless steel cage, it delivers robust performance, high limiting speeds, and long service life. Its pre-lubricated design and effective sealing make it a low-maintenance solution ideal for a wide range of industrial machinery.
6314-ZNR Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning | Benefit |
|---|---|---|
| 6314 | Standard designation for a medium-duty, single row deep groove ball bearing with a 70mm bore, 150mm OD, and 35mm width. | Defines the core bearing dimensions and basic type. |
| Z | Denotes a shielded bearing on one side. | Protects against contaminants while allowing high-speed operation. |
| NR | Indicates the outer ring has a snap ring groove and a fitted snap ring. | Simplifies assembly and provides secure axial location, reducing housing design complexity and cost. |
6314-ZNR Bearing Structural Features & Performance Benefits
- Snap Ring Locating Feature: The integrated snap ring (fitted) on the outer diameter provides a positive axial locating surface. This eliminates the need for complex housing shoulders or locknuts, reducing assembly time and cost.
- Robust Load Capacity: With a high radial dynamic load rating of 24,954 lbf and a radial static load rating of 15,287 lbf, this bearing is built to handle significant radial loads in continuous operation.
- Optimized High-Speed Performance: The combination of a stainless steel cage, precision-ground chrome steel components, and effective shielded design contributes to a high limiting speed of 6,300 rpm.
- Reduced Maintenance & Longevity: Pre-lubricated with grease and protected by a shield, the bearing is sealed against contaminants, promoting a long, maintenance-free service life within its specified temperature range (-30°C to 120°C).
6314-ZNR Bearing Typical Application Areas
The 6314-ZNR is ideally suited for applications requiring secure mounting and reliable performance, including:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- General machinery where efficient assembly and axial location are critical.
