W 608 Bearing Product Overview & Core Advantages
The W 608 is a metric single row deep groove ball bearing engineered for high performance in compact spaces. Constructed entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance and is suitable for a wide operating temperature range. This bearing is designed to primarily handle radial loads and is characterized by its high limiting speed and P0 tolerance class, making it a reliable choice for applications demanding precision and smooth operation.
W 608 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Interpretation |
|---|---|
| W | Designates a stainless steel bearing series. |
| 608 | Indicates the standard boundary dimensions: 8mm bore, 22mm OD, 7mm width. |
| No Seal Suffix | The open (unsealed) construction allows for higher speeds and easier re-lubrication if required, but requires a clean operating environment. |
W 608 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. This also ensures compatibility with the specified temperature range of -30° to 120 °C.
- Deep Groove Raceway: The geometry of the raceways is optimized to support significant radial dynamic load ratings (447 lbf) and moderate axial loads in both directions.
- High-Speed Capability: The open design and precision manufacturing contribute to a high limiting speed of 48,000 rpm, suitable for demanding rotational applications.
- Precision & Reliability: Manufactured to P0 tolerance class and standard CN radial internal clearance, ensuring consistent performance, low noise, and minimal vibration.
- Compliant & Lightweight: The bearing is compliant with ROHS and REACH regulations and has a low weight of 0.011 kg, beneficial for weight-sensitive designs.
W 608 Bearing Typical Application Areas
- Precision Electric Motors and Small Gearboxes
- Medical and Dental Equipment
- Food Processing and Packaging Machinery
- Office Automation Equipment (e.g., printers, scanners)
- Radio Control Models and Small Precision Instruments
- Conveyor System Rollers
