FR188 2rs Bearing Product Overview & Core Advantages
The FR188 2RS is a sealed single row deep groove ball bearing designed for reliable performance in compact spaces. Engineered to primarily handle radial loads, its inch-series dimensions make it ideal for precision applications requiring consistent operation. The bearing features integrated nitrile rubber seals (2RS) on both sides, providing effective protection against contaminants and retaining lubricant. Manufactured to ABEC1 precision tolerances, it offers a dependable balance of performance and value for general industrial use where moderate speeds and loads are present.

| Code Segment | Technical Meaning | Significance |
|---|---|---|
| FR188 | Basic bearing designation with inch dimensions | Identifies the specific size series (0.25" bore × 0.5" OD) |
| 2RS | Double rubber contact seals | Provides effective sealing against dust and moisture while retaining lubricant |
FR188 2rs Bearing Structural Features & Performance Benefits
Robust Construction: Manufactured from chrome steel rings and balls with a stainless steel cage, ensuring durability and corrosion resistance. The deep groove raceway geometry is optimized for efficient radial load distribution.
Enhanced Sealing Performance: The double rubber seals (2RS) provide superior protection in contaminated environments, significantly extending bearing service life by preventing particle ingress and lubricant loss.
Precision Engineering: Built to ABEC1 tolerance class with controlled radial internal clearance (MC3 group), ensuring consistent performance and smooth operation across the specified temperature range of -86 to 230 °F.
Optimized Load Capacity: With a dynamic load rating of 344 lbf and static load rating of 80 lbf, this bearing handles moderate radial loads effectively while maintaining stable operation up to 40,000 rpm limiting speed.
