FR144 2rs Bearing Product Overview & Core Advantages
The FR144 2RS is a sealed single row deep groove ball bearing designed for reliable performance in compact applications. Engineered with inch dimensions, this precision component excels in handling radial loads while offering robust protection against contamination. Its sealed construction and pre-lubricated design ensure long-term operational stability, making it an ideal choice for applications demanding high reliability and minimal maintenance in constrained spaces.
FR144 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Implication |
|---|---|---|
| FR144 | Basic bearing designation with inch dimensions | Defines core bearing dimensions: 0.125" bore × 0.25" OD × 0.1094" width |
| 2RS | Double rubber contact seals on both sides | Provides superior contamination protection and retains lubrication effectively |
FR144 2rs Bearing Structural Features & Performance Benefits
Optimized Load Distribution: Features 7 precision chrome steel balls with 0.03941" diameter, ensuring smooth operation and efficient radial load capacity (54 lbf dynamic / 17 lbf static rating).
Enhanced Sealing Performance: The double rubber seals (2RS) provide excellent exclusion of contaminants while maintaining low friction, contributing to the limiting speed of 67,000 rpm.
Precision Engineering: Manufactured to ABEC1 tolerance class with controlled radial internal clearance (MC3: 0.00008" to 0.0005") for consistent performance and smooth rotation.
Robust Material Construction: Utilizes chrome steel rings and balls with stainless steel cage, ensuring durability and corrosion resistance within the operating temperature range of -86 to 230 °F.
Compact Design: The lightweight construction (0.48 g) with standard inner ring makes it suitable for space-constrained applications requiring reliable bearing performance.
