6207-ZNR/C3 Bearing Product Overview & Core Advantages
The 6207-ZNR/C3 is a single row deep groove ball bearing engineered for high-performance industrial applications. This precision bearing features a shielded design and a C3 radial internal clearance, making it exceptionally suitable for applications with thermal expansion or demanding operating conditions. Its key advantage lies in its ability to handle high radial loads while offering reliable operation. A critical feature is the integral snap ring on the outer ring, which simplifies axial location within a housing, reduces assembly costs, and enhances overall system reliability. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers consistent performance and long service life.
6207-ZNR/C3 Bearing Model Code Explained, Specifications & Naming Convention
- 6207: Standard designation for a single row deep groove ball bearing with a 35mm bore and 72mm outside diameter.
- Z: Denotes a shielded seal on one side, protecting the bearing interior from large contaminants while minimizing friction.
- NR: Indicates the outer ring has a snap ring groove and a snap ring is fitted. This allows for secure axial positioning without the need for a complex housing shoulder.
- C3: Specifies a greater than normal radial internal clearance. This is ideal for applications with elevated operating temperatures or where shaft and housing fits create interference, preventing premature failure due to excessive preload.
6207-ZNR/C3 Bearing Structural Features & Performance Benefits
Robust Construction for High Load Capacity: Built from high-grade chrome steel for both rings, balls, and cage, this bearing ensures high strength and durability. Its deep groove raceway geometry is optimized to support significant radial dynamic load ratings (5778 lbf) and static load ratings (3462 lbf).
Simplified Assembly with Snap Ring: The pre-fitted snap ring (snap ring groove) eliminates the need for complex housing designs with shoulders or end caps. This feature significantly reduces assembly time, lowers manufacturing costs, and provides a reliable method for axial location.
Optimized for Demanding Environments: The C3 clearance provides operational stability in applications prone to thermal expansion, preventing binding and ensuring smooth rotation. The single shield (Z-type) offers a balance between contaminant exclusion and low running torque, contributing to a limiting speed of 9,200 rpm.
6207-ZNR/C3 Bearing Typical Application Areas
The 6207-ZNR/C3 is widely used across various industries due to its versatile design and reliable performance. Common applications include:
- Electric Motors and Gearboxes: For supporting shafts and managing radial loads efficiently.
- Agricultural Machinery: In components requiring robust bearings with easy installation, such as pulleys and idlers.
- Material Handling Equipment: Conveyor systems and rollers benefit from the snap ring for secure mounting.
- Industrial Pumps and Fans: Where the combination of high-speed capability and radial load capacity is critical.
- General Machinery: Any application demanding a cost-effective, high-performance deep groove ball bearing with simplified axial location.
