FR6 Bearing Product Overview & Core Advantages
The FR6 is a precision single row deep groove ball bearing manufactured to inch dimensions, engineered for reliable performance in demanding radial load applications. Featuring an open design and ABEC1 precision class, it delivers consistent operation and is an ideal component for compact assemblies requiring high rotational accuracy. Its robust construction using chrome steel rings and balls ensures durability and a long service life under standard operating conditions.
FR6 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| FR6 | The base bearing designation, indicating a specific inch-size series with a 0.375" bore. |
| Open (Seal Type) | No integral seals or shields, allowing for higher limiting speeds and facilitating custom lubrication schemes. |
| N/A (Lubrication) | Lubrication is required by the user, providing flexibility in selecting the optimal grease or oil for the specific application environment. |
FR6 Bearing Structural Features & Performance Benefits
- High Radial Load Capacity: The single row deep groove raceway and complement of 7 precision balls are optimized to support significant radial dynamic loads up to 638 lbf, making it a robust choice for its compact size.
- Precision & Smooth Operation: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3 group), this bearing ensures low vibration and runout for smooth, accurate rotation.
- Optimized for Speed: The lightweight stainless steel cage effectively retains the balls, contributing to stable performance at limiting speeds up to 32,000 rpm.
- Durable Construction: Components made from chrome steel offer excellent resistance to wear and fatigue, ensuring reliability across its specified temperature range of -86 to 230 °F.
FR6 Bearing Typical Application Areas
This bearing is commonly specified in:
- Small Electric Motors and Gearboxes
- Precision Instrumentation and Medical Devices
- Office Automation Equipment (e.g., printers, scanners)
- Industrial Fans and Blowers
- Various Light-Duty Power Transmission Systems
