FR3 2rs Bearing Product Overview & Core Advantages
The FR3 2RS is a sealed single row deep groove ball bearing designed for reliable performance in compact spaces. Engineered with inch dimensions, this precision bearing excels in applications requiring robust radial load capacity and consistent operation. Its sealed construction provides superior contamination protection, making it ideal for applications where maintenance access is limited. The bearing delivers excellent performance across a wide temperature range while maintaining ABEC1 precision tolerances for smooth, reliable operation.

FR3 2rs Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The optimized raceway design enables excellent radial load capacity (249 lbf dynamic rating) while accommodating moderate axial loads in both directions.
Sealed Protection: Dual nitrile rubber seals (2RS) provide effective barrier against contaminants while retaining lubrication, extending service life in demanding environments.
Precision Engineering: Manufactured to ABEC1 tolerance class with controlled radial internal clearance (MC3: 0.00008" to 0.0005") for smooth operation and reduced vibration.
High-Speed Capability: Stainless steel cage and optimized ball bearing configuration with 7 precision balls enable reliable operation up to 43,000 rpm.
Material Excellence: Chrome steel rings and balls combined with stainless steel cage provide durability and corrosion resistance across a wide temperature range (-86 to 230 °F).
FR3 2rs Bearing Typical Application Areas
- Small Electric Motors: Ideal for fractional horsepower motors requiring reliable bearing performance in compact designs
- Precision Instruments: Suitable for medical devices, optical equipment, and measuring instruments
- Office Automation Equipment: Printers, scanners, and copiers requiring quiet, reliable operation
- Industrial Tools: Small power tools and pneumatic equipment needing durable ball bearing solutions
- Automotive Components: Auxiliary systems, small pumps, and actuator mechanisms
