W 61803-2Z Bearing Product Overview & Core Advantages
The W 61803-2Z is a metric single row deep groove ball bearing engineered for precision and reliability in compact applications. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its ability to efficiently handle radial loads while its shielded design (2Z) provides robust protection against contamination, ensuring long service life with minimal maintenance. This bearing is pre-lubricated with grease, making it ready for immediate use in a wide operating temperature range.
W 61803-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning | Significance |
|---|---|---|
| W | Stainless Steel Bearing | Indicates the bearing rings, balls, and cage are made from stainless steel, providing superior corrosion resistance. |
| 61803 | Basic Bearing Number | Denotes a single row deep groove ball bearing with a 17mm bore, 26mm OD, and 5mm width. |
| 2Z | Shielded on Both Sides | Features non-contact steel shields on both sides, effectively keeping out contaminants while allowing for high limiting speeds. |
W 61803-2Z Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With a width of only 5mm and a weight of 0.0076 kg, this bearing is ideal for applications with severe space and weight constraints.
- Robust Load Capacity: The deep groove raceway and stainless steel construction provide a radial dynamic load rating of 400 lbf and a static rating of 286 lbf, suitable for various radial load conditions.
