211SX Bearing Product Overview & Core Advantages
The 211SX metric ball bearing is a precision single row radial bearing engineered for reliable performance in general industrial applications. Featuring an open design without seals, it is optimized for applications requiring high rotational speeds. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing offers excellent value and consistent operation, making it a robust choice for handling significant radial dynamic loads up to 10881 lbf.
211SX Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 211 | Standard bearing series designation indicating specific bearing dimensions (55mm bore, 100mm OD, 21mm width). |
| SX | Indicates a Chrome Steel cage material, providing good strength and durability for high-speed operation. |
Note: The absence of additional suffixes confirms an open seal type and no pre-applied lubrication.
211SX Bearing Structural Features & Performance Benefits
