W 61801-2RS1/W64F Bearing Product Overview & Core Advantages
The W 61801-2RS1/W64F is a single row deep groove ball bearing designed for high reliability in compact applications. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its sealed design with Solid Oil lubrication, providing long-term, maintenance-free operation by effectively excluding contaminants and retaining lubricant. This bearing is engineered to handle primarily radial loads and is suitable for applications requiring ABEC 1 precision and a wide operating temperature range.
Model Code Breakdown
| Suffix Code | Technical Meaning |
|---|---|
| W | Stainless Steel bearing designator. |
| 61801 | Standard series designation for a metric, single row deep groove ball bearing with a 12 mm bore. |
| 2RS1 | Contact seals on both sides. Provides superior protection against contamination and moisture compared to non-contact shields. |
| W64F | Lubrication with Solid Oil, a polymer matrix saturated with oil. This offers a longer service life, reduced leakage, and consistent performance across the specified temperature range. |
W 61801-2RS1/W64F Bearing Structural Features & Performance Benefits
- Compact and Robust Design: With dimensions of 12x21x5 mm, this bearing offers a high load capacity for its size, making it ideal for space-constrained applications.
- Superior Sealing and Lubrication: The combination of 2RS1 contact seals and Solid Oil (W64F) ensures a sealed-for-life solution. This eliminates relubrication needs, minimizes friction, and protects against premature failure from contamination.
- Corrosion Resistance: The use of stainless steel for the rings and balls makes this bearing suitable for harsh environments where exposure to moisture or chemicals is a concern.
- Precision Performance: Manufactured to ABEC 1 (ISO P0) tolerance class with standard radial internal clearance (CN), it provides reliable and smooth running for a wide range of industrial applications.
