211SFF Bearing Product Overview & Core Advantages
The 211SFF is a single row deep groove ball bearing designed for high-performance applications requiring reliable radial load capacity. As a metric bearing manufactured to ABEC 1 | ISO P0 tolerance class, it offers excellent precision and consistency. Its open design allows for versatile lubrication options, while its robust construction using chrome steel for all core components ensures durability and a long service life. This bearing is engineered for applications demanding a balance of performance, reliability, and cost-effectiveness.
211SFF Bearing Model Code Explained, Specifications & Naming Convention
| 211 | Standard bore diameter code (55 mm) and series designation. |
| SFF | Indicates a specific manufacturer's designation for this bearing's internal geometry and performance characteristics. |
Key Specifications: The open seal type provides flexibility for custom lubrication. The standard CN radial internal clearance is suitable for most common operating conditions.
211SFF Bearing Structural Features & Performance Benefits
Robust Load Capacity: The single row deep groove raceway design is optimized to support significant radial dynamic load ratings of 10881 lbf and static load ratings of 9892 lbf, making it a reliable choice for demanding applications.
Precision Engineering: Manufactured to ABEC 1 | ISO P0 tolerance standards with strict dimensional control on the bore, outside diameter, and width, ensuring smooth operation and easy installation.
High-Speed Capability: With a limiting speed of 7000 rpm, this bearing is capable of operating efficiently in high-velocity scenarios. The chrome steel cage contributes to stability at these speeds.
Material Integrity: The use of chrome steel for the rings, balls, and cage provides high hardness, wear resistance, and a consistent performance across its operating temperature range of -30°C to 120°C.
