6709 Bearing Product Overview & Core Advantages
The 6709 metric ball bearing is a single row, open-type radial bearing engineered for high-performance applications. Designed with precision ABEC-1 tolerance, it delivers reliable operation and consistent performance. Its compact design, with a 6 mm width, makes it ideal for space-constrained assemblies requiring robust radial load capacity. Manufactured from high-grade chrome steel for both rings and balls, this bearing offers excellent durability and is suitable for a wide operating temperature range.
6709 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 67 | Series designation indicating a very thin cross-section for its bore size. |
| 09 | Bore diameter code: 09 corresponds to a 45 mm bore. |
| (No Suffix) | Indicates an open (unsealed) construction, allowing for custom lubrication schemes. |
6709 Bearing Structural Features & Performance Benefits
- High Precision & Stability: Built to ABEC-1 tolerance class with strict dimensional control on the 45 mm bore and 55 mm outside diameter, ensuring smooth, low-vibration operation.
- Optimized Radial Load Capacity: The single row ball bearing design is engineered to handle the specified radial dynamic load rating of 578 lbf and static load rating of 540 lbf effectively.
- High-Speed Capability: Features a lightweight, durable stainless steel cage that maintains ball alignment and integrity at the limiting speed of 4,600 rpm.
- Standard Internal Clearance: The C0 radial internal clearance (0.006mm to 0.023mm) provides a standard fit for most general-purpose applications, accommodating thermal expansion.
- Material Integrity: Components made from chrome steel offer high hardness and wear resistance, while the stainless steel cage provides corrosion resistance.
6709 Bearing Typical Application Areas
This 6709 bearing is suited for a variety of precision industrial applications, including:
- Electric Motors and Small Gearboxes
- Precision Medical Devices and Instrumentation
- Office Automation Equipment (e.g., printers, scanners)
- Low-Torque, High-Speed Spindles
- Various machinery requiring compact ball bearings with standard precision.
