6207-ZNBRJ/C3 Bearing Product Overview & Core Advantages
The 6207-ZNBRJ/C3 is a single row deep groove ball bearing engineered for robust performance in demanding industrial applications. This metric bearing excels in handling significant radial loads and moderate axial loads in both directions. Its key advantages include a snap ring groove on the outer ring for secure axial location, shielded construction for contaminant protection, and a C3 radial internal clearance suitable for applications with thermal expansion or heavy interference fits. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers reliable operation and is designed for high limiting speeds up to 9,200 rpm.
6207-ZNBRJ/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6207 | Basic Bearing Series & Size | Standard deep groove ball bearing with 35mm bore, 72mm OD, 17mm width. |
| ZN | Snap Ring Groove & Shield | "Z" denotes a shield on one side. "N" indicates a snap ring groove on the outer ring. |
| BR | Brass Cage | Indicates a brass (Chrome Steel per spec) cage for strength and high-speed capability. |
| J | Press Steel Cage Design | Specifies the design and material of the cage. |
| /C3 | Radial Internal Clearance | Greater than normal clearance, ideal for applications with expected thermal expansion or heavy interference fits. |
6207-ZNBRJ/C3 Bearing Structural Features & Performance Benefits
Optimized Deep Groove Geometry: The raceway design ensures smooth operation and efficient handling of combined radial and axial loads.
Secure Axial Location: The snap ring groove on the outer ring allows for simplified bearing housing design and prevents axial movement, enhancing system stability.
Contaminant Protection: The non-contact shield helps retain lubrication and excludes larger contaminants, contributing to a longer service life without the torque increase associated with contact seals.
High-Speed Capability: The robust cage design and optimized internal geometry enable a high limiting speed of 9,200 rpm, making it suitable for a wide range of industrial machinery.
Enhanced Durability: Manufactured entirely from chrome steel, all components (rings, balls, cage) provide high strength, wear resistance, and long-term reliability under dynamic load ratings up to 5,778 lbf.
Thermal & Fit Flexibility: The C3 clearance accommodates thermal expansion in the system and allows for heavy interference fits, preventing premature failure due to excessive preload.
6207-ZNBRJ/C3 Bearing Typical Application Areas
- Electric Motors & Generators: A common choice for rotor support due to its high-speed capability and radial load capacity.
- Industrial Gearboxes & Transmissions: Used in various stages for shaft support, benefiting from its robust construction and snap ring location.
- Material Handling Equipment: Conveyor pulleys and rollers where reliable performance under radial load is critical.
- Agricultural Machinery: Implements and powertrain components requiring bearings that can handle moderate contamination and shock loads.
- Pumps & Compressors: Suitable for shaft support applications, leveraging its combination of load handling and speed.
