6407 NR Bearing Product Overview & Core Advantages
The 6407 NR is a single row deep groove ball bearing engineered for superior performance in demanding applications. Its key distinguishing feature is the snap ring (fitted) on the outer ring, which simplifies axial location within a housing, reduces design complexity, and lowers assembly costs. Manufactured to P0 tolerance class with a standard CN radial internal clearance, this bearing offers reliable operation and high precision. Constructed entirely from chrome steel with a stainless steel cage, it delivers excellent durability and a high limiting speed of 10,000 rpm, making it an ideal solution for robust radial load support.
6407 NR Bearing Model Code Explained, Specifications & Naming Convention
- 6407: Basic model number denoting a medium-duty, single row deep groove ball bearing with a 35mm bore and 100mm outside diameter.
- NR: This suffix indicates that the bearing is supplied with a snap ring (fitted) in a groove on the outer ring. This feature acts as a positive locating shoulder, facilitating secure mounting in the housing.
Note: The absence of other suffixes (e.g., for seals or special lubricants) confirms this is an open bearing type.
6407 NR Bearing Structural Features & Performance Benefits
Snap Ring Groove for Simplified Assembly: The integrated snap ring eliminates the need for complex housing shoulders or separate locknuts, enabling a more compact and cost-effective housing design while ensuring secure axial positioning.
High-Speed Capability: The combination of a precision-engineered stainless steel cage and optimized internal geometry allows for a high limiting speed, making it suitable for applications requiring rapid rotation.
Robust Load Capacity: With a dynamic load rating of 12,432 lbf and a static load rating of 6,969 lbf, this bearing is designed to handle significant radial loads, ensuring long service life and operational reliability.
Precision and Durability: Manufactured from high-grade chrome steel and conforming to P0 tolerance, the 6407 NR provides consistent performance, low noise, and vibration levels essential for precision machinery.
6407 NR Bearing Typical Application Areas
The 6407 NR bearing is widely used in industrial applications where ease of assembly and reliable radial load capacity are paramount. Common uses include:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Fans and Blowers
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Any application requiring a snap ring for simplified housing design.
