FR2-6 2rs Bearing Product Overview & Core Advantages
The FR2-6 2RS is a miniature sealed ball bearing designed for precision applications requiring reliable performance in compact spaces. This inch-series bearing features a single-row deep groove construction optimized for radial load applications while accommodating moderate axial loads. Its sealed design with nitrile rubber contact seals provides excellent contamination protection, making it suitable for applications where maintenance-free operation is essential. With an ABEC1 precision class and chrome steel construction, it delivers consistent performance and long service life in demanding environments.
FR2-6 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
| FR2-6 | Bore diameter: 0.125" (1/8"), Outside diameter: 0.375" (3/8") | Compact inch-series dimensions for space-constrained applications |
| 2RS | Double rubber contact seals on both sides | Superior contamination protection and lubricant retention |
Structural Features & Performance Advantages
Sealed Construction: The double nitrile rubber contact seals (2RS) provide excellent protection against contaminants while retaining lubrication, enabling maintenance-free operation in demanding environments.
Precision Engineering: Manufactured to ABEC1 tolerance class with MC3 radial clearance (0.00008" to 0.0005"), ensuring smooth operation and consistent performance across temperature variations.
High-Quality Materials: Chrome steel rings and balls combined with stainless steel cage deliver excellent durability and corrosion resistance, supporting the radial dynamic load rating of 122 lbf and static load rating of 41 lbf.
Optimized Design: The deep groove raceway and 7-ball configuration provide efficient load distribution, while the limiting speed of 53,000 rpm makes it suitable for high-speed applications.
