W 61806 Bearing Product Overview & Core Advantages
The W 61806 is a single row deep groove ball bearing designed for high-performance applications requiring precision and reliability. Engineered with all-stainless steel construction, it offers excellent corrosion resistance and is suitable for a wide operating temperature range. This bearing excels in handling radial loads efficiently while maintaining minimal friction. Its compact design, featuring a 7 mm width, makes it ideal for space-constrained assemblies. Manufactured to P0 tolerance class with CN radial internal clearance, it ensures consistent performance and is compliant with RoHS and REACH standards, making it a robust choice for demanding environments.
Model Code Deep Explanation
| Code Segment | Technical Meaning |
|---|---|
| W | Designates a stainless steel deep groove ball bearing series. |
| 61 | Indicates the bearing series with a specific cross-section and performance characteristics. |
| 806 | Specifies the bore diameter code (06 * 5 = 30 mm bore). |
| (No suffix) | Indicates an open (unsealed) design, allowing for custom lubrication or high-speed operation where minimal drag is critical. |
W 61806 Bearing Structural Features & Performance Benefits
- All-Stainless Steel Construction: The bearing rings, balls, and cage are manufactured from stainless steel, providing superior corrosion resistance and enabling use in harsh or washdown environments.
- High-Speed Capability: The open design and precision engineering contribute to a high limiting speed of 20,000 rpm, suitable for applications requiring rapid rotation.
- Radial Load Capacity: With a dynamic load rating of 805 lbf and a static load rating of 652 lbf, it reliably supports significant radial forces.
- Precision Tolerances: Built to P0 tolerance class and CN radial internal clearance, ensuring smooth operation, low noise, and vibration, which is critical for precision instruments.
- Lightweight & Compact: Weighing only 0.022 kg, it minimizes rotational inertia and is perfect for applications where weight savings are essential.
W 61806 Bearing Typical Application Areas
- Medical and Dental Equipment: Ideal for handpieces, pumps, and small motors where corrosion resistance and reliability are paramount.
- Food Processing and Packaging Machinery: Suitable for conveyors and rollers due to stainless steel's hygiene and washdown compatibility.
- Precision Instruments and Optical Devices: Used in scanners, encoders, and measuring devices requiring high-speed, low-friction operation.
- Small Electric Motors and Gearboxes: Provides efficient support in compact motor designs for appliances, drones, and robotics.
- Laboratory and Analytical Equipment: Employed in centrifuges and mixers that demand precise, contamination-free performance.
