207-ZNRJ Bearing Product Overview & Core Advantages
The 207-ZNRJ is a single row deep groove ball bearing engineered for high-performance applications requiring robust radial load capacity and reliable operation. Its design features a shielded construction on one side and a snap ring groove on the outer ring, offering excellent protection against contamination and simplified axial location within a housing. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing delivers consistent precision and is ideal for applications demanding high reliability and long service life in a compact form factor.
207-ZNRJ Bearing Model Code Explained, Specifications & Naming Convention
- 207: Standard bore diameter code, indicating a 35mm bore.
- Z: Denotes a shielded (non-contact) side, protecting the bearing interior from large particulate contaminants.
- NR: Signifies that the outer ring has a snap ring groove. This feature allows for secure axial positioning, simplifying housing design and assembly.
- J: Indicates that the snap ring is fitted and supplied with the bearing.
207-ZNRJ Bearing Structural Features & Performance Benefits
Optimized for Radial Loads: The single row deep groove raceway geometry is specifically designed to support significant radial dynamic load ratings (6182 lbf), making it a robust choice for a wide range of machinery.
Simplified Assembly & Axial Location: The integrated snap ring on the outer ring eliminates the need for complex housing shoulders or separate retaining components, reducing assembly time and cost.
Contamination Protection: The shielded (Z) design helps retain lubricant and exclude larger contaminants, contributing to enhanced bearing life and reduced maintenance.
Precision & Consistency: Built to ABEC 1 precision class with a standard CN radial internal clearance, this bearing ensures smooth, low-vibration operation suitable for general industrial applications.
207-ZNRJ Bearing Typical Application Areas
The 207-ZNRJ is widely used in various industrial sectors due to its balanced performance and locating feature. Common applications include:
- Electric Motors and Gearboxes
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Industrial Fans and Blowers
- General machinery requiring a reliably located ball bearing with basic sealing.
