W 61804-2RZ Bearing Product Overview & Core Advantages
The W 61804-2RZ is a metric single row deep groove ball bearing designed for exceptional performance in compact applications. Constructed entirely from stainless steel, it offers superior corrosion resistance. Its key advantage lies in its sealed design (2RZ), which provides effective protection against contaminants and retains lubrication, making it a low-maintenance and highly reliable solution for applications requiring long service life and consistent operation under radial loads.
W 61804-2RZ Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Interpretation | Technical Significance |
|---|---|---|
| W | Stainless Steel Bearing | Indicates the bearing rings and balls are made from stainless steel, providing excellent corrosion resistance. |
| 61804 | Basic Bearing Number | Denotes a deep groove ball bearing series with a 20mm bore, 32mm OD, and 7mm width. |
| 2RZ | Non-Contact Rubber Seals (Both Sides) | Features low-friction rubber seals on both sides for effective protection against dust and moisture while retaining grease. |
W 61804-2RZ Bearing Structural Features & Performance Benefits
- Robust Stainless Steel Construction: All components, including rings, balls, and the cage, are manufactured from stainless steel. This ensures high corrosion resistance and makes the bearing suitable for harsh environments and washdown applications.
- Optimized Sealing with 2RZ: The non-contact rubber seals provide an excellent barrier against contaminants without significantly increasing friction, contributing to the bearing's high limiting speed of 24,000 rpm.
- Pre-lubricated for Longevity: The bearing is pre-filled with grease, offering immediate operation and a long service life without the need for re-lubrication, ideal for maintenance-free applications.
- Precision Tolerances: Manufactured to P0 tolerance class and standard CN radial internal clearance, ensuring smooth and reliable running performance.
