61801 Bearing Structural Features & Performance Benefits
- High-Precision Design: Manufactured to a P6 tolerance class, this bearing provides superior running accuracy and minimal vibration, which is critical for high-speed applications.
- Optimized Material Selection: The use of chrome steel for rings and balls, combined with a stainless steel cage, ensures high durability, corrosion resistance, and stable performance across the specified temperature range.
- Radial Load Capacity: The deep groove raceway and single row construction are optimized to efficiently support radial dynamic loads up to 391 lbf and radial static loads up to 206 lbf.
- High-Speed Capability: The lightweight stainless steel cage and precision geometry contribute to a high limiting speed of 43,000 rpm, making it suitable for demanding rotational applications.
- Compact and Lightweight: With dimensions of 12mm x 21mm x 5mm and a weight of only 0.0063 kg, it is ideal for applications where space and weight savings are critical.
61801 Bearing Typical Application Areas
- Precision Electric Motors and small spindle drives
- Office Automation Equipment such as printers and scanners
- Medical and Dental Handpieces requiring high speed and accuracy
