W 617/5 R Bearing Product Overview & Core Advantages
The W 617/5 R is a miniature deep groove ball bearing designed for applications requiring compact dimensions and reliable performance. As a single row radial bearing with an open design, it excels in handling primarily radial loads. Manufactured entirely from stainless steel, it offers excellent corrosion resistance, making it ideal for precision instruments and devices operating in demanding environments. Its small size, high limiting speed, and compliance with RoHS and REACH standards underscore its suitability for high-reliability, compact assemblies.

W 617/5 R Bearing Structural Features & Performance Benefits
Compact & Robust Flange Design: The integrated outer ring flange (flange outer diameter: 9.2 mm) simplifies mounting and axial location, providing a secure and space-saving solution for miniature bearing applications.
High-Speed Capability: The open seal type and optimized stainless steel cage contribute to a high limiting speed of 85,000 rpm, suitable for fast-rotating spindles and small motors.
Corrosion Resistance & Material Integrity: Constructed entirely from stainless steel (rings, balls, and cage), this bearing offers superior resistance to rust and corrosion, ensuring long-term performance and reliability in humid or chemically aggressive environments.
Standard Precision & Clearance: Built to P0 tolerance class and standard CN radial internal clearance, it provides consistent and predictable performance for a wide range of general precision applications.
