W 61703 R-2ZS Bearing Product Overview & Core Advantages
The W 61703 R-2ZS is a single row deep groove ball bearing designed for high precision and reliable operation in compact spaces. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its ability to handle radial loads efficiently while its shielded design (2ZS) provides robust protection against contaminants. Pre-lubricated with grease, this bearing is ready for immediate use, making it an ideal, maintenance-friendly solution for applications demanding high reliability and long service life.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| W | Stainless Steel Bearing |
| 61703 | Basic bearing designation, indicating a single row deep groove design with a 17mm bore, 23mm OD, and 4mm width. |
| R | Flanged outer ring, providing a simplified and secure mounting solution. |
| 2ZS | Contact seals on both sides. The "Z" denotes a steel shield, and "S" indicates a contact-type seal, offering superior protection against dust and moisture compared to non-contact shields. |
W 61703 R-2ZS Bearing Structural Features & Performance Benefits
- Compact & Robust Flange Design: The integrated flange (24.5 mm outer diameter) facilitates easy and precise axial location, simplifying housing design and reducing assembly time.
- Superior Sealing & Contamination Resistance: The 2ZS contact seals on both sides effectively exclude contaminants, making the bearing suitable for harsh environments and contributing to a long operational lifespan.
- High Precision & Smooth Operation: Manufactured to P0 tolerance class with a CN radial internal clearance, this bearing ensures consistent performance, low noise, and low vibration.
- Maintenance-Free & Ready-to-Use: Pre-lubricated with grease, the bearing is protected from the outset and requires no initial lubrication, enabling immediate installation and reducing maintenance overhead.
- Corrosion Resistance: All components, including rings, balls, and cage, are made from stainless steel, providing excellent resistance to rust and corrosion, ideal for applications exposed to moisture or chemicals.
