63003-2RS1/W64 Bearing Product Overview & Core Advantages
The 63003-2RS1/W64 is a single row deep groove ball bearing designed for exceptional reliability in demanding applications. This metric bearing features integral seals and pre-lubrication, making it a maintenance-free solution. Its core advantages include a high radial dynamic load rating of 1360 lbf, robust construction using chrome steel for all critical components, and a wide operating temperature range. Engineered to ABEC 1 | ISO P0 tolerance standards, it delivers consistent performance and long service life for general industrial use.
63003-2RS1/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Implication |
|---|---|---|
| 2RS1 | Contact rubber seals on both sides | Provides superior contamination protection, retaining lubricant and excluding moisture and debris. |
| W64 | Solid Oil lubrication | Ensures maintenance-free operation and reliable lubrication over a wide temperature range (-30° to 120 °C). |
63003-2RS1/W64 Bearing Structural Features & Performance Benefits
- Optimized Deep Groove Raceway: The single-row design with deep raceways is engineered for high radial load capacity, efficiently handling the specified 1360 lbf dynamic load.
- Sealed and Pre-Lubricated Design: The combination of 2RS1 contact seals and W64 Solid Oil eliminates the need for re-lubrication, reduces friction, and significantly extends bearing service life by protecting against lubricant loss and contamination.
- High-Quality Material Integrity: Manufactured entirely from chrome steel (rings, balls, and cage), this bearing ensures high strength, durability, and consistent performance under the specified limiting speed of 13,000 rpm.
- Standardized Precision: Conforms to ABEC 1 | ISO P0 tolerance class and CN radial internal clearance, guaranteeing smooth and quiet operation with minimal vibration for general precision applications.
63003-2RS1/W64 Bearing Typical Application Areas
This versatile and robust bearing is ideally suited for a wide range of applications, including:
- Small Electric Motors and Gearboxes
- Industrial Fans and Blowers
- Conveyor System Idlers and Pulleys
- Agricultural Machinery
- Automotive Auxiliary Units (e.g., alternators, pumps)
- General Machinery requiring reliable, maintenance-free operation.
