W 633-2RS1 Bearing Product Overview & Core Advantages
The W 633-2RS1 is a metric single row deep groove ball bearing engineered for high reliability in compact applications. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its sealed design (2RS1) with pre-lubricated grease, making it a maintenance-free solution that effectively protects against contamination. This bearing is designed to primarily handle radial loads and is optimized for smooth operation, making it ideal for applications demanding long service life and consistent performance.

| Code Segment | Technical Meaning |
|---|---|
| W | Stainless Steel Bearing |
| 633 | Bearing series, indicating a specific dimension series with a 3mm bore, 13mm OD, and 5mm width. |
| 2RS1 | Contact seals on both sides. The RS1 seal provides effective protection against dust and moisture while retaining lubricant. |
W 633-2RS1 Bearing Structural Features & Performance Benefits
- Corrosion Resistance: Manufactured from stainless steel rings, cage, and balls, this bearing is suitable for applications exposed to moisture and corrosive environments.
- Sealed & Lubricated for Life: The integral 2RS1 contact seals shield the bearing interior from contaminants. Pre-filled grease lubrication ensures smooth operation and eliminates the need for re-lubrication, offering a true maintenance-free solution.
- Radial Load Capacity: The deep groove raceway and single-row design are optimized to efficiently support radial loads, providing reliable performance in a compact bearing size.
- Standard Precision & Clearance: Built to P0 tolerance class and standard CN radial internal clearance, this bearing guarantees consistent and reliable operation for a wide range of general-purpose applications.
