| FRW1 | Specific series designation for this inch-sized, flanged, single row ball bearing. |
| zz | Indicates the bearing is equipped with shields on both sides (2Z). This provides effective protection against contaminant ingress. |
FRW1zz Bearing Structural Features & Performance Benefits
- Robust Construction & High Rigidity: The single row design with a stainless steel cage maintains ball alignment and provides stable, rigid support for the shaft.
- Effective Contamination Protection: The 300 Series Stainless Steel shields on both sides help retain lubricant and exclude contaminants, enhancing bearing life in dusty or dirty environments.
- Optimized for Radial Loads: With a dynamic load rating of 44 lbf and a static load rating of 12 lbf, this bearing is engineered to handle significant radial forces.
- Precision & Speed: Manufactured to ABEC1 standards with a controlled radial internal clearance (MC3: 0.00008" to 0.0005"), it ensures smooth running and is capable of operating at a limiting speed of 90,000 rpm.
- Material Quality: Components made from Chrome Steel (rings and balls) offer excellent hardness and wear resistance, contributing to long-term reliability.
FRW1zz Bearing Typical Application Areas
This bearing is suited for a wide range of compact, high-speed devices, including:
- Small precision motors and spindles
- Medical and dental handpieces
- Optical encoders and instrumentation
