61801-2Z/GFF/R806 Bearing Product Overview & Core Advantages
The 61801-2Z/GFF/R806 is a metric single row deep groove ball bearing designed for high-performance applications requiring compact design and reliable operation. This shielded bearing excels in handling radial loads efficiently while offering protection from contaminant ingress. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides consistent precision and is suitable for applications demanding high rotational accuracy and long service life.
61801-2Z/GFF/R806 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance |
|---|---|---|
| -2Z | Non-Contact Shield on Both Sides | Provides effective contamination protection while maintaining low friction and high-speed capability. |
| /GFF | Specific Grease Filling (Factory Filled) | Indicates the bearing is pre-lubricated with a specific grease formulation for immediate use. |
| /R806 | Grease Type Designation | Specifies the high-performance grease used, optimized for the bearing's operating temperature range. |
61801-2Z/GFF/R806 Bearing Structural Features & Performance Benefits
Optimized Single Row Design: The deep groove raceway and high-quality chrome steel construction (rings, balls, and cage) enable smooth operation and effective radial load distribution.
Shielded Protection: The -2Z shields protect the internal components from dust and debris, enhancing bearing life in contaminated environments without significantly increasing friction.
Precision & Speed: Built to ABEC 1 precision with CN radial internal clearance, this bearing supports a limiting speed of 43,000 rpm, making it suitable for high-speed applications.
Ready-to-Use Lubrication: The factory-applied /GFF/R806 grease ensures optimal performance from the first rotation across the specified temperature range (-30°C to 120°C), reducing initial setup requirements.
61801-2Z/GFF/R806 Bearing Typical Application Areas
- Small Electric Motors: Ideal for spindle and rotor support in miniature and micro motors.
- Precision Instruments: Used in optical encoders, medical devices, and laboratory equipment requiring smooth, precise rotation.
- Office Automation Equipment: Suitable for printers, scanners, and copiers where compact size and reliability are critical.
