6221/W64F Bearing Product Overview & Core Advantages
The 6221/W64F is a single row deep groove ball bearing designed for reliable performance in demanding industrial applications. Engineered to primarily accommodate radial loads, this bearing features a solid oil lubrication system, ensuring long-term, maintenance-free operation. Its high precision ABEC 1 (ISO P0) tolerance and robust construction with all-chrome steel components make it an excellent choice for applications requiring consistent performance and durability. The open design allows for easy integration and is ideal for high-speed operations up to 3,500 rpm.
Model Code In-Depth Analysis
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| W64 | Solid Oil Lubrication | Provides a sealed-for-life lubrication system, eliminating relubrication needs and preventing contamination. |
| F | Machined Brass Cage | Offers high strength, excellent guidance, and suitability for high-speed applications. |
6221/W64F Bearing Structural Features & Performance Benefits
- Robust Construction: Manufactured entirely from chrome steel (rings, balls, and cage), providing high hardness, wear resistance, and a long operational lifespan.
- Maintenance-Free Operation: The integrated Solid Oil lubrication system ensures consistent performance without the need for relubrication, reducing maintenance costs and downtime.
- High-Speed Capability: The combination of the precision-machined brass cage (F suffix) and optimized solid oil allows for a high limiting speed of 3,500 rpm.
- Precision Performance: Manufactured to ABEC 1 (ISO P0) tolerance standards with a standard CN radial internal clearance, ensuring smooth and quiet running, which is critical for precision machinery.
- High Load Capacity: With a radial dynamic load rating of 29,900 lbf and a radial static load rating of 23,605 lbf, it reliably handles significant radial forces.
