FRW2-5 Bearing Product Overview & Core Advantages
The FRW2-5 is a single row deep groove ball bearing designed for high-performance applications requiring reliable radial load capacity in a compact, inch-sized format. Manufactured to ABEC1 precision tolerances, this bearing features an extended inner ring with a flange for secure axial location, making it ideal for space-constrained assemblies. Its open design allows for versatile lubrication options to meet specific operational requirements, delivering consistent performance across a wide temperature range from -86 to 230 °F.
FRW2-5 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| FRW2-5 | Specific manufacturer designation for this inch-series, single row deep groove ball bearing with extended inner ring and flange. |
| Open (Seal type) | No integral seals or shields, allowing for custom lubrication schemes and higher potential speeds, but requiring a clean operating environment. |
FRW2-5 Bearing Structural Features & Performance Benefits
Optimized Radial Load Capacity: The deep groove raceway and six high-precision chrome steel balls enable efficient handling of the 107 lbf dynamic radial load rating, providing robust support in demanding applications.
Precision & Stability: Built to ABEC1 tolerance class with a controlled MC3 radial internal clearance, this bearing ensures smooth, low-vibration operation, contributing to overall system accuracy.
Simplified Assembly & Axial Location: The extended inner ring and integrated flange (0.359" outer diameter) facilitate easy mounting and provide a positive shoulder for axial positioning, reducing design complexity.
High-Speed Capability: The lightweight stainless steel cage and open construction contribute to a high limiting speed of 110,000 rpm, making it suitable for high-velocity spindles and rotors.
FRW2-5 Bearing Typical Application Areas
- Small Precision Motors and Spindles
- Medical and Dental Handpieces
- Optical Encoders and Precision Instruments
- Office Automation Equipment (e.g., high-speed scanners, printers)
- Textile Machinery guide rollers and tensioning systems
