W 61805-2RS1 Bearing Product Overview & Core Advantages
The W 61805-2RS1 is a single row deep groove ball bearing designed for high performance in compact spaces. As a sealed bearing constructed entirely from stainless steel, it offers excellent corrosion resistance and reliable operation. Its primary advantage lies in its ability to efficiently handle radial loads while being pre-lubricated for maintenance-free service. This makes it an ideal choice for applications demanding high reliability, long service life, and operation within a wide temperature range from -30°C to 120°C.
W 61805-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Code | Technical Meaning |
|---|---|---|
| Basic Designation | W 61805 | Stainless steel deep groove ball bearing series with 25mm bore, 37mm OD, and 7mm width. |
| Seal Type | 2RS1 | Features contact seals on both sides, providing effective protection against contaminants and retaining lubricant. |
W 61805-2RS1 Bearing Structural Features & Performance Benefits
- Robust Construction & Corrosion Resistance: Manufactured from stainless steel for the rings, balls, and cage, this bearing is inherently resistant to rust and corrosion, suitable for harsh environments.
- Effective Sealing: The 2RS1 double-contact seals shield the bearing interior from dust, moisture, and other contaminants, significantly extending its service life and enabling maintenance-free operation.
- Ready-to-Use Lubrication: The bearing is pre-lubricated with grease, making it immediately operational and suitable for applications where re-lubrication is difficult.
- Precision & Load Capacity: Built to P0 tolerance class with CN radial internal clearance, it ensures consistent performance. It offers a dynamic load rating of 760 lbf and a static load rating of 562 lbf, handling significant radial loads for its compact bearing dimensions (25x37x7 mm).
- High-Speed Capability: With a limiting speed of 11,000 rpm, it is well-suited for applications requiring high rotational velocities.
