S6903zz Bearing Product Overview & Core Advantages
The 17mm Bore Metric Ball Bearing is a precision single row radial ball bearing engineered for reliable performance in demanding applications. Constructed entirely from stainless steel, it offers excellent corrosion resistance. This bearing is designed to primarily handle radial loads with a high limiting speed of 19,800 rpm. Its compact design, featuring a 7mm width, makes it ideal for applications where space is limited and high reliability is required. Manufactured to ABEC-1 tolerance class, it ensures consistent and smooth operation.

| Feature | Code/Value | Technical Significance |
|---|---|---|
| Bore Diameter | 17 mm | Specifies the inner diameter for shaft mounting. |
| Seal Type | Shielded | Provides protection from contaminants while allowing high-speed operation. |
| Tolerance Class | ABEC-1 | Defines the precision level for running accuracy and vibration. |
| Internal Clearance | C0 (Normal) | Standard radial internal clearance for general operating conditions. |
S6903zz Bearing Structural Features & Performance Benefits
- Full Stainless Steel Construction: The bearing rings, balls, and cage are made from stainless steel, providing superior corrosion resistance and making it suitable for harsh environments, including those requiring washdown or exposure to chemicals.
- Shielded Design: The integrated shield effectively retains lubricant and excludes larger particulate contaminants, enhancing bearing life and reliability without the added friction of contact seals.
- High-Speed Capability: The combination of a stainless steel cage, optimized geometry, and shielded design allows for a high limiting speed, making it suitable for applications like small spindles and high-RPM machinery.
- Precision Performance: Manufactured to ABEC-1 standards, this bearing ensures low noise and smooth rotation, which is critical for applications sensitive to vibration.
- Radial Load Capacity: With a dynamic load rating of 929 lbf and a static load rating of 518 lbf, it is robust enough to handle significant radial forces for its size.
S6903zz Bearing Typical Application Areas
This versatile stainless steel ball bearing is commonly specified in:
- Food and Beverage Processing Equipment (conveyors, mixers)
- Medical and Laboratory Devices
- Chemical Handling Pumps and Valves
- Precision Instruments and Optical Devices
