W 61901-2RS1 Bearing Product Overview & Core Advantages
The W 61901-2RS1 is a metric single row deep groove ball bearing designed for exceptional performance in compact spaces. Constructed entirely from stainless steel, it offers superior corrosion resistance. Its key advantage lies in its sealed design (2RS1) with pre-lubricated grease, providing long-term, maintenance-free operation and reliable protection against contaminants. This bearing is engineered to handle primarily radial loads and is capable of high-speed operation up to 19,000 rpm, making it an ideal precision bearing for applications demanding reliability and durability.
W 61901-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Description | Technical Significance |
|---|---|---|
| W | Stainless Steel Bearing | Indicates the bearing rings and balls are made from stainless steel, offering excellent corrosion resistance. |
| 61901 | Size Series & Bore Diameter | "619" is the series code for extra-small, thin-section bearings. "01" indicates a 12 mm bore diameter. |
| 2RS1 | Sealing | Specifies two (2) contact seals (RS1) made of NBR rubber, providing superior protection against moisture and dust. |
W 61901-2RS1 Bearing Structural Features & Performance Benefits
- Robust Stainless Steel Construction: All components, including the rings, balls, and cage, are manufactured from stainless steel. This ensures high corrosion resistance, making the bearing suitable for harsh environments and washdown applications.
- Effective Sealing for Long Life: The two-sided contact seals (2RS1) effectively retain the factory-applied grease lubrication and exclude contaminants. This combination delivers a maintenance-free, long-service-life solution.
- Optimized for High Speeds: The single-row deep groove ball bearing design, combined with the stainless steel cage and effective sealing, allows for a high limiting speed of 19,000 rpm.
- Precise Dimensional Control: Manufactured to P0 tolerance class and standard CN radial internal clearance, this bearing ensures reliable and consistent performance in a wide range of applications.
W 61901-2RS1 Bearing Typical Application Areas
This versatile sealed bearing is ideally suited for applications requiring compact size, corrosion resistance, and low maintenance. Key industries and equipment include:
- Medical and Dental Equipment
- Food and Beverage Processing Machinery
- Small Precision Electric Motors
- Office Automation Equipment (Printers, Scanners)
