FRW2-6 Bearing Product Overview & Core Advantages
The FRW2-6 is a single row deep groove ball bearing designed for exceptional performance in compact applications. Manufactured to ABEC1 precision standards, this inch-series bearing delivers reliable radial load capacity while maintaining minimal cross-sectional dimensions. Its extended inner ring design facilitates easier mounting and secure positioning in assemblies requiring precise axial location. The bearing's chrome steel construction ensures durability and consistent operation across a wide temperature range from -86 to 230 °F.
Model Code Technical Breakdown
| Code Element | Technical Meaning | Performance Impact |
|---|---|---|
| FRW2-6 | Standard inch-size designation | Defines critical bearing dimensions: 0.125" bore × 0.375" OD × 0.1094" width |
| Open | No seals or shields | Enables higher limiting speed (53,000 rpm) but requires controlled environment |
| Extended Inner Ring | Inner ring protrudes beyond bearing width | Simplifies mounting and provides positive axial location |
| MC3 Clearance | Standard radial internal clearance (0.00008" to 0.0005") | Optimized for general purpose applications with moderate temperature variations |
FRW2-6 Bearing Structural Features & Performance Benefits
Optimized Ball Configuration: The bearing incorporates seven precision balls with 0.0625" diameter, strategically arranged to maximize radial load capacity (122 lbf dynamic / 41 lbf static) while maintaining smooth operation.
Premium Material Construction: Manufactured from chrome steel rings and stainless steel cage, this combination provides excellent wear resistance and corrosion protection, ensuring long service life in demanding conditions.
High-Speed Capability: The open design combined with stainless steel cage enables operation at 53,000 rpm limiting speed, making it suitable for high-rotation applications where friction minimization is critical.
Precision Engineering: Built to ABEC1 tolerance class with tight dimensional controls (bore/OD tolerance: -0.0003" to 0"), ensuring consistent performance and reliable interchangeability in precision assemblies.
FRW2-6 Bearing Typical Application Areas
- Small precision motors and miniature DC motors requiring high-speed operation
- Medical devices and laboratory equipment where compact dimensions and reliability are essential
- Optical encoders and precision instrumentation requiring minimal runout and vibration
- Office automation equipment including printers, scanners, and copiers
