FR2-6zz Bearing Product Overview & Core Advantages
The FR2-6ZZ is a precision miniature ball bearing designed for applications demanding compact size and reliable performance. As a single row deep groove ball bearing, it is optimized to handle primarily radial loads efficiently. Its inch-series dimensions, including a 1/8" bore, make it ideal for space-constrained assemblies. The bearing features integral shielded protection, preserving internal integrity and extending service life in various operating environments. Manufactured to ABEC1 precision tolerances, it offers a dependable balance of performance and value for high-volume, precision applications.
FR2-6zz Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Benefit |
|---|---|---|
| FR2-6 | Bore Size Code (0.125") & Series Designation | Specifies the compact inch-dimension bearing size. |
| ZZ | Double Shields (One on each side) | Provides effective protection against contaminants like dust, without significantly increasing rotational torque. Lubrication is required. |
FR2-6zz Bearing Structural Features & Performance Benefits
- Robust Construction: The single row deep groove raceway and complement of 7 precision balls enable smooth operation and efficient radial load capacity.
- High-Quality Materials: Rings and balls made from Chrome Steel provide high hardness and wear resistance. The Stainless Steel cage ensures dimensional stability and corrosion resistance.
- Contaminant Protection: The double 300 Series Stainless Steel shields (ZZ) help retain lubricant and exclude larger particulate matter, enhancing bearing reliability.
- Precision Performance: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3), ensuring consistent running accuracy and low noise.
- Wide Temperature Range: Suitable for operations from -86 to 230 °F, accommodating various environmental conditions.
FR2-6zz Bearing Typical Application Areas
This bearing is commonly specified in:
- Small Precision Motors (e.g., stepper motors, DC micromotors)
- Office Automation Equipment (printers, scanners, copiers)
- Medical Devices and Instrumentation
- Computer Disk Drives and Cooling Fans
- Radio Control Models and Small Gearboxes
- Various Instrumentation and Low-Power Drive Systems
