W211-PPB3 Bearing Product Overview & Core Advantages
The W211-PPB3 is a single row deep groove ball bearing engineered for high reliability in general industrial applications. As a metric bearing with an open design, it is optimized for carrying primarily radial loads. Its construction from high-grade chrome steel ensures durability and consistent performance. This bearing is characterized by its standard ABEC 1 (ISO P0) precision and CN radial internal clearance, making it a versatile and cost-effective solution for a wide range of machinery.
Model Code Breakdown
| Suffix / Prefix | Technical Meaning |
|---|---|
| W211 | Basic bearing designation, defining the core dimensions (55mm bore, 100mm OD, 21mm width). |
| -PPB3 | Manufacturer-specific suffix. Typically indicates design features such as internal specifications, cage type, or performance enhancements not covered by standard codes. |
| (Implied: Open) | The absence of a seal/shield suffix (e.g., -2RS, -2Z) confirms an open bearing design, allowing for custom lubrication regimes. |
W211-PPB3 Bearing Structural Features & Performance Benefits
- Robust Construction: Manufactured from chrome steel for both rings, balls, and cage, this bearing offers high strength and resistance to wear, ensuring a long operational life under radial dynamic loads up to 10881 lbf.
- High-Speed Capability: The single row deep groove geometry and precision-ground components enable a limiting speed of 7000 rpm, suitable for a variety of high-speed applications.
- Precision & Stability: Built to ABEC 1 (ISO P0) tolerance class with a CN radial internal clearance, it provides reliable running accuracy and minimal vibration, contributing to overall system stability.
- Application Flexibility: The open seal type provides maximum flexibility for lubrication, allowing it to be used with oil, grease, or in environments where re-lubrication is part of the maintenance schedule. It operates effectively within a temperature range of -30°C to 120°C.
W211-PPB3 Bearing Typical Application Areas
This single row ball bearing is widely used in sectors requiring dependable rotational performance. Key applications include:
- Electric Motors and Generators
- Industrial Gearboxes
- Material Handling Conveyors
- Agricultural Machinery
