61900-2RS1/W64 Bearing Product Overview & Core Advantages
The 61900-2RS1/W64 is a miniature deep groove ball bearing designed for compact applications requiring high reliability. This sealed single row bearing excels in handling radial loads and is pre-lubricated with Solid Oil for long-term, maintenance-free operation. Its metric dimensions (10mm bore, 22mm OD, 6mm width) and precision ABEC 1 tolerance make it ideal for applications where space is limited and consistent performance is critical.
61900-2RS1/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| -2RS1 | Contact rubber seals on both sides | Provides excellent contamination protection, retaining lubrication effectively |
| /W64 | Pre-filled with Solid Oil polymer lubrication | Enables maintenance-free operation across the entire temperature range (-30° to 120°C) |
61900-2RS1/W64 Bearing Structural Features & Performance Benefits
- Compact Design & High Precision: The single row deep groove design with ABEC 1 (ISO P0) tolerance ensures smooth operation and precise positioning in confined spaces.
- Robust Load Capacity: Manufactured entirely from chrome steel (rings, balls, and cage), it offers a dynamic load rating of 607 lbf and a static load rating of 286 lbf, providing reliable performance under radial stresses.
- Maintenance-Free Longevity: The combination of 2RS1 contact seals and Solid Oil (W64) lubrication eliminates relubrication needs, prevents lubricant leakage, and ensures consistent performance, making it a true sealed-for-life bearing.
- Stable Operational Range: With a standard CN radial internal clearance and a broad operating temperature range, the bearing delivers stable performance in various environments.
61900-2RS1/W64 Bearing Typical Application Areas
This bearing is ideally suited for small, high-speed, and precision mechanisms, including:
- Small Electric Motors (e.g., miniature DC motors, stepper motors)
- Office Automation Equipment (e.g., printers, scanners, copiers)
- Medical Devices and Dental Handpieces
- Precision Instruments and optical devices
- Computer Cooling Fans and small gearboxes
