61816-2RZ Bearing Product Overview & Core Advantages
The 61816-2RZ is a single row deep groove ball bearing designed for exceptional performance in compact spaces. This precision bearing features integral contact seals (2RZ) and pre-lubrication, making it a maintenance-free solution for applications demanding high reliability. Its fundamental advantage lies in its ability to efficiently handle radial loads while accommodating moderate axial loads in both directions. With a P6 tolerance class and optimized internal geometry, it delivers smooth operation and extended service life, making it ideal for high-speed and high-precision environments.
61816-2RZ Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Implication |
|---|---|---|
| 61816 | Basic bearing designation indicating a metric deep groove ball bearing with 80mm bore, 100mm OD, and 10mm width. | Defines the core bearing dimensions and type. |
| -2RZ | Specifies non-contact rubber seals on both sides of the bearing. | Provides excellent protection against contaminants while maintaining a high limiting speed of 6,300 rpm. Ensures long-term lubrication retention. |
61816-2RZ Bearing Structural Features & Performance Benefits
- Optimized Internal Geometry & High-Grade Materials: Manufactured from chrome steel rings and balls with a stainless steel cage, this bearing ensures high durability and corrosion resistance. The precise raceway grinding and ball sizing contribute to smooth operation and low noise/vibration levels.
- Superior Sealing & Lubrication: The 2RZ non-contact rubber seals effectively shield the internal components from dust and moisture without significantly increasing friction. Combined with factory-fitted grease lubrication, this creates a sealed-for-life unit, eliminating the need for re-lubrication.
- High-Speed Capability: The lightweight stainless steel cage and optimized internal design enable a high limiting speed of 6,300 rpm, making it suitable for demanding high-speed applications.
- Robust Load Capacity: With a dynamic load rating of 2855 lbf and a static load rating of 2518 lbf, this bearing offers reliable performance under significant radial loads.
61816-2RZ Bearing Typical Application Areas
This versatile sealed ball bearing is widely used in industries and equipment requiring compact, reliable, and maintenance-free rotary motion. Key applications include:
- Electric Motors and small generators
- Precision Gearboxes and transmission systems
- Industrial Fans and Blowers
- Office automation equipment (e.g., printers, copiers)
