W 6003 Bearing Product Overview & Core Advantages
The W 6003 is a metric single row deep groove ball bearing engineered for precision radial load applications. Constructed entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance and is suitable for a wide operating temperature range. Its open design and P0 tolerance class make it a reliable and cost-effective solution for applications requiring high rotational accuracy and durability in various industrial environments.
W 6003 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| W | Manufacturer's prefix/series identifier |
| 60 | Deep groove ball bearing series |
| 03 | Bore diameter code (17 mm) |
| (No Suffix) | Indicates an open (unsealed) bearing with standard radial internal clearance (CN) and no pre-lubrication. |
W 6003 Bearing Structural Features & Performance Benefits
- All-Stainless-Steel Construction: Provides superior corrosion resistance, making it ideal for applications exposed to moisture, chemicals, or washdown environments. Ensures long service life and consistent performance.
- High-Speed Capability: The stainless steel cage and optimized geometry contribute to a high limiting speed of 28,000 rpm, suitable for demanding rotational applications.
- Radial Load Capacity: As a single row deep groove ball bearing, it is primarily designed to support significant radial loads (1111 lbf dynamic, 708 lbf static) efficiently.
- Precision & Low Friction: Manufactured to P0 tolerance class with CN radial clearance, ensuring smooth operation, low noise, and minimal vibration.
- Flexible Lubrication: The open seal type allows for the application of specialized lubricants tailored to specific operational needs, though it requires an external sealing arrangement in contaminated environments.
W 6003 Bearing Typical Application Areas
This bearing is commonly used in:
- Medical and Dental Equipment
- Food Processing and Packaging Machinery
- Precision Instruments and Optical Devices
- Small Electric Motors and Fans
- Agricultural and Marine Equipment (where corrosion resistance is critical)
