6701 Bearing Product Overview & Core Advantages
The 6701 is a metric single row deep groove ball bearing engineered for high-performance applications requiring reliable radial load support. Manufactured to ABEC-1 precision tolerances, this compact bearing (12mm bore, 18mm OD, 4mm width) delivers consistent operation and excellent value. Its open design allows for versatile lubrication options, making it suitable for a wide range of industrial machinery where controlled internal clearance and dependable performance are critical.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 67 | Series designation, indicating a very thin section, ultra-light series bearing. |
| 01 | Bore diameter code, corresponding to a 12mm bore. |
| Open (No Seal/Shield suffix) | The bearing is supplied without seals or shields, allowing for high-speed operation and custom lubrication schemes. |
6701 Bearing Structural Features & Performance Benefits
- High-Speed Capability: The open design and stainless steel cage minimize friction and drag, enabling a high limiting speed of 15,000 rpm for efficient operation.
- Radial Load Capacity: Optimized deep groove raceway geometry effectively supports radial dynamic loads up to 209 lbf and radial static loads up to 120 lbf.
- Precision & Stability: Manufactured to ABEC-1 tolerance class with a standard C0 radial internal clearance (0.003mm to 0.018mm), ensuring smooth and precise rotation with minimal runout.
- Durable Construction: Components made from chrome steel (rings and balls) offer high wear resistance and durability, while the stainless steel cage provides excellent corrosion resistance.
- Compact & Lightweight: With a minimal cross-section and a weight of only 3.1 grams, it is ideal for space-constrained and weight-sensitive applications.
6701 Bearing Typical Application Areas
