627/HR11QN Bearing Product Overview & Core Advantages
The 627 is a metric single row deep groove ball bearing designed for outstanding performance in general industrial applications. Engineered to primarily handle radial loads, its open design and precision manufacturing make it a versatile and cost-effective solution. A key advantage is its ABEC 1 precision class, ensuring reliable operation and smooth running. Constructed entirely from durable chrome steel, it offers excellent resistance to wear and a long service life, operating effectively within a temperature range of -30°C to 120°C.
627/HR11QN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 627 | The basic bearing designation, indicating a metric, single row deep groove ball bearing with a 7 mm bore, 22 mm OD, and 7 mm width. |
| Open (Implied) | No seals or shields are present, allowing for higher limiting speeds and easy re-lubrication, but requiring a clean operating environment. |
| ABEC 1 | ISO P0 | Specifies the tolerance class, denoting standard manufacturing precision for reliable general-purpose use. |
| CN (Radial Clearance) | Indicates a normal radial internal clearance, suitable for most common operating conditions and fits. |
627/HR11QN Bearing Structural Features & Performance Benefits
- Optimized Deep Groove Raceway: The deep, continuous raceways on both rings are fundamental to the bearing's ability to carry significant radial dynamic load ratings (629 lbf) and accommodate moderate axial loads in both directions.
- High-Grade Chrome Steel Construction: All components, including the rings, balls, and pressed steel cage, are made from chrome steel. This ensures high hardness, excellent wear resistance, and a long operational lifespan.
- Open Design for High-Speed Operation: The absence of seals minimizes friction, allowing the bearing to achieve its maximum limiting speed of 30,000 rpm. This makes it an excellent choice for high-speed applications where heat generation must be minimized.
- Standard Precision for Reliable Performance: Manufactured to ABEC 1 (ISO P0) tolerance standards, this bearing provides consistent and reliable running accuracy, reducing vibration and noise in the assembly.
627/HR11QN Bearing Typical Application Areas
This versatile single row ball bearing is widely used across various industries due to its robust design and high-speed capability. Common applications include:
- Small Electric Motors and Gearboxes
- Precision Instruments and Measuring Devices
- Office Machinery and Computer Fans
- Light-duty Conveyor Systems
- Power Tools and Household Appliances
