W 61807 Bearing Product Overview & Core Advantages
The W 61807 is a single row deep groove ball bearing engineered for high-performance applications requiring precision and reliability. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its open design facilitates high-speed operation, while its P0 tolerance class and CN radial internal clearance ensure consistent performance under radial loads. This bearing is characterized by its compact cross-section, with a 7 mm width, making it an ideal solution for space-constrained assemblies demanding high limiting speeds and robust dynamic load capacity.
W 61807 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| W | Designates a stainless steel deep groove ball bearing. |
| 61 | Indicates the bearing series, defining its cross-sectional dimensions and load characteristics. |
| 807 | Specifies the bore diameter: 35 mm. |
| (No Seal Suffix) | The absence of a seal suffix (e.g., 2Z, RS) confirms an open (unsealed) design, optimized for minimal friction and high-speed performance. |
W 61807 Bearing Structural Features & Performance Benefits
- All-Stainless-Steel Construction: The rings, balls, and cage are manufactured from stainless steel, providing superior corrosion resistance and enabling operation in harsh environments and within a wide temperature range of -30° to 120 °C.
- High-Speed Capability: The open design and precision-ground components minimize friction and heat generation, allowing for a high limiting speed of 18,000 rpm.
- Robust Load Capacity: Engineered to handle significant radial dynamic loads (834 lbf) and radial static loads (753 lbf), ensuring durability and long service life.
- Precision Engineering: Manufactured to P0 tolerance class with standard CN radial internal clearance, guaranteeing consistent running accuracy and smooth operation, which is critical for precision applications.
W 61807 Bearing Typical Application Areas
The W 61807 is ideally suited for a wide range of demanding applications across various industries, including:
- Food and Beverage Processing Equipment (due to its corrosion-resistant stainless steel construction and compliance with ROHS/REACH)
- Medical and Laboratory Instruments
- High-Speed Electric Motors and Spindles
- Precision Gearboxes and Power Transmission Systems
- Agricultural and Marine Machinery (in components exposed to corrosive elements)
