FR1zz Bearing Product Overview & Core Advantages
The FR1zz is a precision miniature ball bearing designed for demanding applications requiring compact size and reliable performance. As a single row radial ball bearing with shielded construction, it excels in handling radial loads with high efficiency. Its inch-series dimensions make it ideal for replacement in American-designed equipment and precision instruments where space is at a premium. Manufactured to ABEC1 tolerance class, this bearing offers a dependable balance of performance and cost-effectiveness for a wide range of industrial and commercial uses.
FR1zz Bearing Model Code Explained, Specifications & Naming Convention
| Feature | Designation | Technical Significance |
|---|---|---|
| Seal Type | Shielded | Features non-contact shields (typically denoted by ZZ suffix) that protect against large contaminants while minimizing friction, contributing to the high limiting speed. |
| Internal Clearance | MC3 | Specifies a radial internal clearance group (0.00008" to 0.0005") suitable for applications with moderate operational temperatures and tight fits. |
| Cage Material | Stainless Steel | Provides excellent corrosion resistance and durability, ensuring stable performance and long service life. |
FR1zz Bearing Structural Features & Performance Benefits
- Optimized for Radial Loads: The single row design with a complement of 6 precision balls provides a robust solution for applications dominated by radial loads, offering a dynamic load rating of 44 lbf and a static load rating of 12 lbf.
- High-Speed Capability: The combination of a stainless steel cage, shielded design, and precision grinding allows for a high limiting speed of 90,000 rpm, making it a capable high-speed bearing.
- Precision & Stability: Manufactured to ABEC1 standards with a controlled MC3 internal clearance, this bearing ensures smooth, low-vibration operation, which is critical for sensitive equipment.
- Corrosion Resistance: The use of 300 Series Stainless Steel for the shields and cage, along with Chrome Steel rings, provides enhanced protection against corrosion in challenging environments.
FR1zz Bearing Typical Application Areas
This versatile miniature bearing is commonly specified in:
- Small Precision Motors: Ideal for spindle and rotor support in DC motors, stepper motors, and servo motors.
- Medical and Dental Devices: Used in handheld tools, pumps, and scanners where reliability and compact bearing dimensions are paramount.
- Office Automation Equipment: Critical components in printers, scanners, and copiers.
- Instrumentation and Control Systems: Provides precise rotational support in encoders, sensors, and gauges.
- Robotics and Automation: Suitable for joints, guides, and small actuators in compact robotic assemblies.
