SFR1810 Bearing Product Overview & Core Advantages
The SFR1810 is a single row deep groove ball bearing manufactured to ABEC1 precision standards. Engineered for radial load applications, this inch-series bearing features a compact design with a 0.3125" bore. Its construction from stainless steel throughout (rings, balls, and cage) provides excellent corrosion resistance, making it suitable for demanding environments. The bearing requires lubrication and is designed for reliable performance across a wide temperature range from -86 to 230 °F.

SFR1810 Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The raceway design enables efficient handling of radial loads while accommodating moderate axial loads in both directions.
Stainless Steel Construction: All components (rings, balls, cage) are manufactured from stainless steel, providing superior corrosion resistance and suitability for washdown environments or applications requiring chemical compatibility.
Precision Engineering: Manufactured to ABEC1 tolerance class with controlled radial internal clearance (MC3 group: 0.00008" to 0.0005") ensures consistent performance and smooth operation.
High-Speed Capability: With a limiting speed of 36,000 rpm, the bearing is optimized for high-speed applications through precision grinding and balanced design.
Flanged Design: The integrated flange (0.547" OD) facilitates easy mounting and axial location, simplifying installation in housing designs.
SFR1810 Bearing Typical Application Areas
- Medical Devices: Surgical handpieces, dental tools, and diagnostic equipment
- Precision Instruments: Optical encoders, measuring devices, and laboratory equipment
- Small Motors: Stepper motors, servo motors, and miniature DC motors
- Office Automation: Printers, scanners, and copier mechanisms
