W 6305 Bearing Product Overview & Core Advantages
The W 6305 is a metric single row deep groove ball bearing engineered for exceptional performance in demanding applications. Constructed entirely from stainless steel (rings, balls, and cage), it offers superior corrosion resistance. Its open design and P0 tolerance class make it a reliable choice for applications requiring smooth operation and handling primarily radial loads. With a high limiting speed and robust dynamic and static load ratings, this bearing is built for durability and long service life in various industrial environments.
W 6305 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| W | Indicates the bearing is manufactured from stainless steel. |
| 63 | Series designation, indicating a medium width dimension. |
| 05 | Bore diameter code; corresponds to a 25 mm bore diameter. |
| (No Suffix) | The absence of additional suffixes confirms an open (unsealed) design, standard radial internal clearance (CN), and no pre-lubrication. |
W 6305 Bearing Structural Features & Performance Benefits
- All-Stainless-Steel Construction: Provides excellent resistance to rust and corrosion, making it ideal for harsh environments, including those exposed to moisture or certain chemicals.
- Deep Groove Raceway: The geometry of the raceway is optimized to support not only high radial loads but also moderate axial loads in both directions.
- Stainless Steel Cage: Ensures dimensional stability and reliable performance across the specified temperature range from -30°C to 120°C.
- Open Design & High-Speed Capability: The unsealed nature and precision manufacturing contribute to a high limiting speed of 17,000 rpm, suitable for high-speed applications.
- Precision Tolerances: Manufactured to P0 tolerance class with controlled internal clearance (CN), ensuring consistent performance and ease of installation in precision assemblies.
