W 61906 Bearing Product Overview & Core Advantages
The W 61906 is a metric single row deep groove ball bearing engineered for precision applications requiring high reliability. Constructed entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance. Its open design and P0 tolerance class make it a versatile and cost-effective solution for handling primarily radial loads in various industrial environments. The bearing is characterized by its compact cross-section and low weight, providing a robust and efficient solution for space-constrained assemblies.

| Code Segment | Technical Meaning |
|---|---|
| W | Designates a stainless steel bearing series. |
| 61906 | Indicates the bearing size series '619' with a 30mm bore diameter and 9mm width. |
| Open | No seals or shields, allowing for higher speeds and custom lubrication but requiring a clean operating environment. |
W 61906 Bearing Structural Features & Performance Benefits
- High Corrosion Resistance: The all-stainless steel construction ensures reliable performance in humid or corrosive environments, making it suitable for food processing, medical, and marine applications.
- Precision Performance: Manufactured to P0 tolerance class and standard CN radial internal clearance, this bearing provides consistent and smooth operation for general precision needs.
- High-Speed Capability: The open design and stainless steel cage contribute to a high limiting speed of 19,000 rpm, reducing friction and heat generation.
- Versatile Lubrication: As a non-lubricated (None) and open bearing, it offers the flexibility to be used with a wide range of lubricants tailored to specific application requirements, including high-temperature or food-grade greases.
W 61906 Bearing Typical Application Areas
This bearing is ideally suited for applications where corrosion resistance and moderate precision are key. Common uses include:
- Medical and Dental Equipment
- Food and Beverage Processing Machinery
- Optical and Precision Instruments
- Agricultural Machinery
- Electric Motors and Small Gearboxes
