SFR6 Bearing Product Overview & Core Advantages
The SFR6 is a high-precision, inch series single row deep groove ball bearing engineered for demanding applications. Constructed entirely from stainless steel, it offers excellent corrosion resistance and reliable performance. Its core advantages include a robust radial dynamic load rating of 574 lbf and the ability to operate at high speeds up to 28,800 rpm. The open design ensures low friction and is ideal for applications requiring supplemental lubrication for optimal performance across a wide temperature range from -86 to 230 °F.
SFR6 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SFR6 | Standard bearing designation in the inch series. |
| Open (Seal Type) | No integral seals or shields. Allows for custom lubrication schemes and minimizes friction for high-speed operation. |
| ABEC1 | Specifies the precision tolerance class, ensuring consistent running accuracy. |
| MC3 | Defines the standard radial internal clearance group (0.00008" to 0.0005"), suitable for a wide range of operating conditions. |
SFR6 Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & Single Row Design: The geometry is optimized for handling significant radial loads efficiently. The single row construction contributes to a compact bearing width of only 0.2188", saving space in design.
- Full Stainless Steel Construction: Both rings, the ball complement (7 balls), and the cage are made from stainless steel, providing superior corrosion resistance and durability in harsh environments.
- High-Speed Capability: The combination of an open design, a precision-stamped stainless steel cage, and a ball diameter of 0.1563" enables smooth operation at the specified limiting speed.
- Precision Engineering: Manufactured to ABEC1 tolerance class with controlled internal clearance, this bearing ensures consistent performance, low vibration, and long service life.
SFR6 Bearing Typical Application Areas
- Medical and Dental Equipment: Surgical handpieces, pumps, and scanners where corrosion resistance and reliability are critical.
- Food and Beverage Processing Machinery: Conveyors and mixers requiring frequent washdowns and stainless steel components.
- Precision Instruments and Optical Devices: High-speed scanners, encoders, and gauging equipment.
- Small Electric Motors and Gearboxes: Especially in applications where standard metric sizes are not suitable.
