61805-2RS1/W64 Bearing Product Overview & Core Advantages
The 61805-2RS1/W64 is a single row deep groove ball bearing designed for exceptional performance in compact spaces. This metric bearing features a sealed construction and is engineered to primarily handle radial loads. Its key advantages include a high limiting speed of 24,000 rpm, reliable operation provided by Soild Oil lubrication, and robust construction from chrome steel components. It is an ideal solution for applications demanding high reliability, low maintenance, and compact design.
61805-2RS1/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| 61805 | Basic designation for a single row deep groove ball bearing with 25mm bore, 37mm OD, and 7mm width. | Defines the standard bearing dimensions and type. |
| 2RS1 | Contact seals on both sides made of NBR. | Provides effective protection against contaminants and retains lubricant, enhancing bearing life. |
| W64 | Lubricated with Soild Oil, a polymer-based lubricant. | Enables maintenance-free operation, prevents oil leakage, and is suitable for a wide temperature range. |
61805-2RS1/W64 Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & Single Row Design: Optimized for high radial load capacity and smooth operation at high speeds.
- Sealed Construction (2RS1): The double-sided contact seals effectively shield the bearing from dust, moisture, and other contaminants, while securely retaining the lubricant. This contributes to long service life and reliability in harsh environments.
- Soild Oil Lubrication (W64): This integrated lubrication system eliminates the need for re-lubrication, prevents leakage, and ensures consistent performance across the specified temperature range from -30°C to 120°C. It is a key factor in achieving the high limiting speed.
- Precision Manufacturing (ABEC 1 | ISO P0): Manufactured to standard precision tolerances, ensuring consistent quality, smooth running, and low noise levels.
- Chrome Steel Construction: All critical components (rings, balls, cage) are made from high-quality chrome steel, providing excellent durability, wear resistance, and load-carrying capability.
61805-2RS1/W64 Bearing Typical Application Areas
- Small Electric Motors and Gear Motors
- Office Automation Equipment (e.g., Printers, Scanners)
- Cooling Fans and Blowers
- Precision Instruments and Medical Devices
- Automotive Auxiliary Units (e.g., Idlers, Tensioners)
