W 61703 Bearing Product Overview & Core Advantages
The W 61703 is a metric single row deep groove ball bearing engineered for high precision and reliable performance in compact spaces. Its open design and construction from stainless steel throughout (rings, balls, and cage) provide excellent corrosion resistance. This bearing is specifically designed to handle radial loads efficiently and is characterized by its very small cross-section, with a width of only 4 mm, making it an ideal solution for applications where space and weight are critical constraints.
W 61703 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| W | Manufacturer's prefix |
| 61 | Bearing series, indicating a very thin cross-section |
| 7 | Bore diameter code (specific to manufacturer's system) |
| 03 | Outside diameter code (specific to manufacturer's system) |
| Open | No seals or shields, allowing for higher speeds and easy re-lubrication if required. |
W 61703 Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With a bearing width of just 4 mm and a weight of only 0.0035 kg, this bearing is engineered for applications with severe space and weight limitations.
- High Corrosion Resistance: The use of stainless steel for all critical components ensures reliable operation in harsh or washdown environments.
- Precision Performance: Manufactured to P0 tolerance class and standard CN radial internal clearance, this bearing provides consistent and precise running, which is crucial for sensitive mechanisms.
- High-Speed Capability: The open design and stainless steel cage contribute to a high limiting speed of 38,000 rpm, making it suitable for high-speed applications.
- Material Compliance: The bearing is ROHS and REACH compliant, meeting stringent environmental and safety standards.
