W 61900-2RS1 Bearing Product Overview & Core Advantages
The W 61900-2RS1 is a metric single row deep groove ball bearing designed for high performance in compact spaces. Engineered with stainless steel rings, balls, and cage, it offers excellent corrosion resistance. A key feature is its integral contact seals (2RS1) on both sides, which effectively retain grease and exclude contaminants, making it a maintenance-free solution. This bearing is optimized to handle primarily radial loads and is capable of high-speed operation up to 20,000 rpm, making it ideal for applications demanding high reliability and long service life.
Model Code Breakdown
| Code Segment | Technical Meaning |

| 61900 | Bearing series, indicating a very small cross-section with a 10mm bore. |
| 2RS1 | Bearing with Rubber Contact Seals on both sides. Provides superior protection against contamination and grease leakage. |
W 61900-2RS1 Bearing Structural Features & Performance Benefits
- Robust Sealed Construction: The 2RS1 contact seals are molded from synthetic rubber and are in light contact with the inner ring land. This design provides excellent protection against moisture and solid contaminants, ensuring a long, maintenance-free operational life.
- Corrosion Resistance: Manufactured entirely from stainless steel, this bearing is highly resistant to rust and corrosion, making it suitable for harsh environments and applications requiring frequent washdowns.
- High-Speed Capability: The precision-ground components and optimized grease lubrication allow for a high limiting speed of 20,000 rpm, supporting demanding applications.
- Precision and Reliability: Manufactured to P0 (Normal) tolerance class and standard CN radial internal clearance, it delivers consistent performance and smooth operation.
W 61900-2RS1 Bearing Typical Application Areas
The W 61900-2RS1 is ideally suited for applications where compact size, corrosion resistance, and sealed-for-life operation are critical. Common uses include:
- Precision Instruments and medical devices
- Small Electric Motors and miniature gearboxes
- Office automation equipment, such as printers and scanners
- Food and beverage processing machinery (due to stainless steel construction)
- Robotics and small precision drives
