W 61901 R Bearing Product Overview & Core Advantages
The W 61901 R is a single row deep groove ball bearing designed for exceptional performance in compact spaces. This metric series bearing features an open design and is constructed entirely from stainless steel, providing excellent corrosion resistance. Its primary advantage lies in its ability to handle high-speed applications (up to 40,000 rpm) while supporting significant radial loads. The combination of a small cross-section, high precision (P0 tolerance class), and robust construction makes it ideal for applications demanding reliability and high rotational accuracy.

W 61901 R Bearing Structural Features & Performance Benefits
- Compact Flange Design: The integrated flange (26.5mm diameter) enables easy axial positioning and secure housing fit, reducing assembly complexity and cost.
- All-Stainless Steel Construction: Rings, balls, and cage are manufactured from stainless steel, offering superior corrosion resistance and suitability for harsh environments, including washdown applications.
- High-Speed Capability: The open design, combined with a precision-machined stainless steel cage and CN radial internal clearance, allows for a limiting speed of 40,000 rpm, making it an excellent high-speed bearing.
- Radial Load Capacity: Engineered to support a dynamic load rating of 564 lbf and a static load rating of 328 lbf, ensuring reliable performance under significant radial stresses.
- Precision Performance: Manufactured to P0 tolerance class with tight bore and outside diameter tolerances, guaranteeing consistent running accuracy and smooth operation.
W 61901 R Bearing Typical Application Areas
- Medical and Dental Equipment: Small motors, pumps, and handheld tools requiring corrosion resistance and high speed.
- Food Processing and Packaging Machinery: Conveyor rollers, mixers, and fillers where washdown and hygiene are critical.
- Precision Instruments and Optical Devices: Scanners, encoders, and small gearboxes demanding high accuracy and minimal vibration.
- Small Electric Motors and Fans: Main shaft support in compact, high-RPM motors.
- Office Automation Equipment: Printers, copiers, and scanners utilizing the bearing's flange for easy mounting.
