W 61701-2RS1 Bearing Product Overview & Core Advantages
The W 61701-2RS1 is a miniature deep groove ball bearing designed for compact, high-precision applications. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its sealed design (2RS1), which provides robust protection against contaminants and retains lubrication, making it a low-maintenance and highly reliable solution for applications demanding long service life and consistent performance under radial loads.

W 61701-2RS1 Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With a 4mm width and a weight of only 0.0029 kg, this bearing is ideal for space-constrained and weight-sensitive applications.
- Robust Sealing: The 2RS1 contact seals effectively shield the internal components from dust, moisture, and other contaminants, while also retaining the pre-applied grease lubrication.
- Corrosion Resistance: Manufactured entirely from stainless steel (rings, balls, and cage), this bearing is suitable for use in harsh environments and applications requiring washdown.
- Reliable Performance: The deep groove raceway and optimized internal geometry enable smooth operation and reliable handling of radial dynamic loads up to 118 lbf.
