6013 NR Bearing Product Overview & Core Advantages
The 6013 NR is a single row deep groove ball bearing designed for exceptional radial load capacity and reliable performance in demanding applications. Its key distinguishing feature is the snap ring (fitted) on the outer ring, which provides secure axial location within a housing, simplifying design and assembly. Manufactured from high-grade chrome steel with a stainless steel cage, this bearing offers robust durability and consistent operation. With a standard CN radial internal clearance and P0 tolerance class, it delivers precise and dependable performance for a wide range of industrial machinery.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6013 | Standard bearing series designation, indicating a metric, single row deep groove ball bearing with a 65mm bore, 100mm OD, and 18mm width. |
| NR | Signifies that the bearing is supplied with a snap ring fitted into a groove on the outer ring. This acts as a locating feature, preventing axial movement of the bearing within the housing. |
6013 NR Bearing Structural Features & Performance Benefits
- Snap Ring Groove for Secure Location: The integrated snap ring eliminates the need for complex housing shoulders or end caps, reducing part count, assembly time, and overall system cost. This feature provides excellent resistance against creep and axial displacement.
- High Radial Load Capacity: The optimized deep groove raceway and chrome steel construction enable the bearing to handle significant radial dynamic load ratings of 7171 lbf, making it suitable for applications with substantial radial forces.
- Robust Cage for Stable Operation: The stainless steel cage ensures smooth guidance of the balls at high speeds, contributing to a limiting speed of 9,000 rpm and enhanced operational stability.
- Standard Internal Clearance & Tolerances: The CN radial internal clearance and P0 tolerance class provide a balance of fit and performance for most general industrial applications, ensuring reliable and predictable behavior.
- Open Design for Flexibility: The open (non-sealed) design allows for the application of specific lubricants suited to the operational environment, offering flexibility for specialized lubrication requirements.
6013 NR Bearing Typical Application Areas
The 6013 NR bearing is ideally suited for applications where secure axial location and high 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
- Various types of General Industrial Machinery requiring a cost-effective and easily installed bearing solution.
