FRW166zz Bearing Product Overview & Core Advantages
The FRW166zz is a single row deep groove ball bearing designed for precision radial load applications. Featuring a shielded construction and manufactured to ABEC1 precision tolerances, this bearing offers reliable performance in compact spaces. Its extended inner ring facilitates easier mounting and positioning. Engineered for applications requiring consistent operation within a broad temperature range, this bearing delivers excellent value for general-purpose industrial use.
FRW166zz Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| zz | Indicates double-sided non-contact steel shields. This provides effective protection against contaminant ingress while minimizing friction, contributing to the bearing's limiting speed of 50,000 rpm. |
FRW166zz Bearing Structural Features & Performance Benefits
- Robust Construction: The single row deep groove raceway and chrome steel components provide reliable radial load capacity with a dynamic rating of 136 lbf.
- Contamination Protection: The 300 series stainless steel shields effectively exclude contaminants while allowing high-speed operation without significant torque increase.
- Precision Performance: Manufactured to ABEC1 tolerance class with controlled radial internal clearance (MC3: 0.00008" to 0.0005") for consistent operation and reduced vibration.
- High-Speed Capability: The stainless steel cage and optimized ball complement (8 balls of 0.0625" diameter) enable operation at speeds up to 50,000 rpm.
- Extended Inner Ring: The extended inner ring design (0.1562" width) provides improved mounting stability and facilitates easier installation and axial positioning.
