W 61804-2Z Bearing Product Overview & Core Advantages
The W 61804-2Z is a single row deep groove ball bearing designed for exceptional performance in demanding applications. Constructed entirely from stainless steel, it offers superior corrosion resistance. Its key advantage lies in its ability to handle radial loads efficiently while its shielded (2Z) design provides protection against contaminant ingress, ensuring long-term reliability and reduced maintenance. This compact and precision-engineered bearing is ideal for applications requiring high-speed operation and consistent performance.

|---|---|
| W | Stainless Steel Bearing |
| 61804 | Bearing series and size designation (Metric, 20mm bore, 32mm OD, 7mm width) |
| 2Z | Bearing with shields on both sides for contaminant protection. The bearing is pre-lubricated with grease. |
W 61804-2Z Bearing Structural Features & Performance Benefits
- Corrosion Resistance: Manufactured from stainless steel rings, balls, and cage, this bearing is suitable for applications exposed to moisture and corrosive environments.
- High-Speed Capability: The deep groove raceway and optimized stainless steel cage contribute to a high limiting speed of 24,000 rpm, making it an excellent high-speed bearing.
- Sealed & Pre-Lubricated: The non-contact shields (2Z) protect the internal components from dust and debris while retaining the factory-fill grease, enabling maintenance-free operation for the life of the bearing in many applications.
- Precision & Load Capacity: Built to P0 tolerance class and standard CN radial internal clearance, it ensures smooth, quiet running and reliable handling of the specified radial dynamic and static load ratings.
W 61804-2Z Bearing Typical Application Areas
This versatile bearing is commonly specified in:
- Food & Beverage Processing Equipment (for corrosion resistance and cleanliness)
- Medical and Dental Devices (for precision and reliability)
- Chemical Handling Pumps (for corrosion resistance)
- Precision Instruments and Optical Devices
- Electric Motors and Small Gearboxes requiring high-speed operation
