61800-2Z Bearing Product Overview & Core Advantages
The 61800-2Z is a metric single row deep groove ball bearing featuring integral shields for robust protection. Engineered for high-speed operation and reliable performance in compact spaces, this bearing is designed to handle primarily radial loads. Its shielded construction and pre-lubrication ensure long service life with minimal maintenance, making it an ideal choice for applications demanding high precision and operational reliability.
61800-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Advantage |
|---|---|---|
| 61800 | Series designation for extra small, thin-section deep groove ball bearings | Compact design for space-constrained applications |
| 2Z | Bearing with shields on both sides | Effective contamination protection, retaining lubricant |
61800-2Z Bearing Structural Features & Performance Benefits
- High-Speed Capability: The combination of a stainless steel cage, optimized internal geometry, and effective grease lubrication enables operation at limiting speeds up to 38,000 rpm.
- Robust Load Capacity: Manufactured from chrome steel for both rings and balls, this bearing offers a dynamic load rating of 387 lbf and a static load rating of 187 lbf, ensuring durability under demanding conditions.
- Precision & Rigidity: Built to P6 tolerance class with a CN radial internal clearance, it provides consistent running accuracy and contributes to system stability.
- Maintenance-Free Operation: The ZZ shield design effectively seals the bearing, and the factory-applied grease lubrication provides long-term, maintenance-free performance within its specified temperature range (-30°C to 120°C).
61800-2Z Bearing Typical Application Areas
This bearing is widely used in applications requiring compact size, high speed, and reliability, including:
- Small precision electric motors
- Office automation equipment (printers, scanners)
- Medical devices and instrumentation
- Small fans and blowers
- Robotics and miniature gearboxes
