61806-2RZ Bearing Product Overview & Core Advantages
The 61806-2RZ is a metric single row deep groove ball bearing designed for high-performance applications requiring compact design and reliable operation. Its key advantage lies in its ability to efficiently handle radial loads while offering a sealed construction for enhanced protection and longevity. Manufactured with precision P6 tolerance and pre-lubricated with grease, this bearing is engineered for applications demanding high rotational accuracy, smooth operation, and minimal maintenance in a space-saving package.
Model Code Breakdown
- 61806: Basic series designation for a metric single row deep groove ball bearing with a 30mm bore and 42mm outside diameter.
- -2RZ: Suffix indicating the bearing is fitted with non-contact seals on both sides. The "RZ" seal type offers effective protection against contaminants while maintaining low friction and enabling high limiting speeds.
61806-2RZ Bearing Structural Features & Performance Benefits
Robust Construction & High Precision: Built from chrome steel rings and balls with a stainless steel cage, the bearing ensures durability and corrosion resistance. The P6 tolerance class provides superior dimensional accuracy and running precision for smooth, vibration-free operation.
Effective Sealing & Lubrication: The 2RZ non-contact seals effectively shield the internal components from dust and moisture, extending service life. The bearing is pre-lubricated with grease, making it ready-to-mount and maintenance-free for a wide temperature range of -30°C to 120°C.
High-Speed Capability: The combination of the low-friction seal design, optimized internal geometry, and effective lubrication contributes to a high limiting speed of 16,000 rpm, making it suitable for demanding high-speed applications.
61806-2RZ Bearing Typical Application Areas
The 61806-2RZ is ideally suited for a variety of compact and high-speed machinery, including:
- Small Electric Motors and Spindles
- Precision Gearboxes
- Office Automation Equipment (e.g., printers, scanners)
- Medical Devices and Instrumentation
- Fan and Blower Units
