W 61900 R Bearing Product Overview & Core Advantages
The W 61900 R is a metric single row deep groove ball bearing designed for high-performance applications requiring precision and reliability. This stainless steel bearing features an open design without seals, enabling high-speed operation up to 45,000 rpm. Its compact flanged design (outer diameter 25 mm) provides secure mounting and positioning in housings. Engineered to handle primarily radial loads with excellent dynamic capacity (526 lbf), it offers superior corrosion resistance and operates across a wide temperature range (-30° to 120°C). The bearing's P0 tolerance class and CN radial clearance ensure consistent performance in precision applications.

W 61900 R Bearing Structural Features & Performance Benefits
All-Stainless Steel Construction: The bearing rings, balls, and cage are manufactured from stainless steel, providing excellent corrosion resistance and durability in challenging environments. This makes the bearing suitable for applications requiring frequent washdown or exposure to chemicals.
Flanged Design Advantage: The integrated flange (25mm outer diameter, 1.5mm thickness) enables precise axial positioning and simplifies housing design. This feature eliminates the need for additional components for bearing location, reducing assembly time and cost.
High-Speed Capability: With a limiting speed of 45,000 rpm, this bearing excels in high-rotation applications. The open design minimizes friction and heat generation, while the stainless steel cage ensures reliable operation at elevated speeds.
Precision Engineering: Manufactured to P0 tolerance class with CN radial internal clearance, the bearing delivers consistent performance and smooth operation. The tight dimensional tolerances (bore: -0.008mm to 0, OD: -0.009mm to 0) ensure precise fit and reliable performance.
