FR168 2rs Bearing Product Overview & Core Advantages
The FR168 2RS is a high-performance inch-series ball bearing engineered for precision applications requiring reliable operation. As a single row deep groove ball bearing featuring integral rubber seals (2RS), it provides effective protection against contaminants while retaining lubrication. This bearing is designed to handle significant radial loads and is characterized by its compact design, making it ideal for space-constrained assemblies. Manufactured to ABEC1 precision class with optimized internal geometry, it delivers smooth operation and extended service life in demanding industrial environments.
FR168 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Implication |
|---|---|---|
| FR168 | Standard inch-series bearing designation | Defines basic dimensions: 0.25" bore × 0.375" OD × 0.125" width |
| 2RS | Double rubber contact seals on both sides | Provides superior contaminant exclusion and lubricant retention |
FR168 2rs Bearing Structural Features & Performance Benefits
Optimized Internal Geometry: The deep groove raceway and precision-ground chrome steel balls (11 balls, 0.03941" diameter) ensure smooth rotation and efficient load distribution. The stainless steel cage maintains proper ball spacing for stable operation at the limiting speed of 48,000 rpm.
Enhanced Sealing System: The double nitrile rubber seals (2RS) create an effective barrier against dust, moisture, and other contaminants while retaining lubricant. This design significantly extends bearing service life in challenging environments.
Precision Manufacturing: Manufactured to ABEC1 tolerance class with controlled radial internal clearance (MC3: 0.00008" to 0.0005"), ensuring consistent performance and reliable operation. The tight dimensional tolerances on bore, outside diameter, and width facilitate precise fitment in assemblies.
Robust Load Capacity: With a dynamic radial load rating of 71 lbf and static radial load rating of 31 lbf, this bearing delivers reliable performance under substantial radial stresses. The flange design (0.422" OD, 0.036" thickness) provides secure mounting and additional stability.
