61800/W64F Bearing Product Overview & Core Advantages
The 61800/W64F is a miniature deep groove ball bearing designed for compact applications requiring high precision and reliable performance. As a single row, open type bearing, it excels in handling primarily radial loads and is characterized by its extremely small cross-section. Manufactured to ABEC 1 | ISO P0 tolerance class, it offers consistent quality for general precision applications. A key feature is its integrated Soild Oil lubrication, which provides long-term, maintenance-free operation within a wide temperature range, making it an ideal choice for space-constrained and permanently lubricated assemblies.
61800/W64F Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 61800 | Series designation for extra-small, thin-section deep groove ball bearings. |
| W64 | Identifier for the specific Soild Oil lubrication system. |
| F | Suffix indicating a specific radial internal clearance group (matching the specified CN clearance). |
61800/W64F Bearing Structural Features & Performance Benefits
- Compact Design & High Precision: With a bore diameter of just 10 mm and a width of 5 mm, this bearing offers an exceptionally small footprint. Its ABEC 1 precision ensures smooth, low-vibration operation, crucial for sensitive mechanisms.
- Robust Load Capacity: Despite its miniature size, it features a radial dynamic load rating of 387 lbf and a radial static load rating of 187 lbf, providing reliable performance under load.
- Maintenance-Free Operation: The integrated Soild Oil lubrication eliminates the need for re-lubrication, reduces contamination risk, and ensures consistent performance from -30°C to 120°C.
- Optimized for Speed: The bearing achieves a limiting speed of 48,000 rpm, supported by the stable chrome steel cage and effective solid lubrication.
61800/W64F Bearing Typical Application Areas
This miniature deep groove ball bearing is ideally suited for applications where space and weight are critical constraints. Common uses include:
- Small Precision Motors (e.g., in drones, RC models, and miniature fans)
- Medical and Dental Handpieces
- Office Automation Equipment (e.g., printers, scanners)
- Instrumentation and Measurement Devices
- Textile Machinery guides and tensioners
