FR1810 Bearing Product Overview & Core Advantages
The FR1810 is a single row deep groove ball bearing designed for precision radial load applications. Engineered with inch dimensions (0.3125" bore), it offers a compact, high-performance solution for industrial equipment requiring reliable operation. Its open design allows for custom lubrication schemes, while the stainless steel cage and chrome steel construction ensure durability and consistent performance across a wide temperature range (-86 to 230 °F). This bearing is ideal for applications demanding ABEC1 precision and efficient operation at speeds up to 40,000 rpm.
FR1810 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| FR1810 | Manufacturer's base designation for this specific inch-series bearing size and type. |
| Open (Seal Type) | No integral seals or shields. Allows for high-speed operation and application-specific lubrication. |
| ABEC1 | Tolerance class defining standard precision levels for runout and dimensional accuracy. |
| MC3 | Specified radial internal clearance group (0.00008" to 0.0005") for standard operating conditions. |
FR1810 Bearing Structural Features & Performance Benefits
- Optimized Radial Load Capacity: The single row deep groove raceway and 12 high-precision chrome steel balls provide a dynamic load rating of 104 lbf and static rating of 50 lbf, ensuring reliable performance under substantial radial stresses.
- High-Speed Capability: The combination of an open design, lightweight stainless steel cage, and precise ABEC1 tolerances enables a limiting speed of 40,000 rpm, making it suitable for demanding rotational applications.
- Precision & Stability: Tight dimensional tolerances on the bore diameter, outside diameter, and controlled radial internal clearance (MC3) contribute to smooth, low-vibration operation and accurate shaft positioning.
- Robust Construction: Manufactured from chrome steel for rings and balls with a stainless steel cage, the bearing offers excellent resistance to wear and corrosion, supporting a long service life.
FR1810 Bearing Typical Application Areas
- Small Electric Motors and Gear Motors
- Precision Instrumentation and Medical Devices
- Office Automation Equipment (e.g., printers, scanners)
- Computer Cooling Fans and Spindles
- Light-duty Industrial Drives and Power Tools
