6303-2RSJEM Bearing Product Overview & Core Advantages
The 6303-2RS JEM is a single row deep groove ball bearing designed for reliable performance in demanding applications. Featuring integrated rubber seals (2RS) on both sides, this sealed bearing offers excellent protection against contaminants and retains lubricant effectively. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides consistent operation and is pre-lubricated for immediate use. Its robust chrome steel construction ensures durability and a long service life, making it an ideal choice for applications requiring radial load capacity and operational reliability.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6303 | Basic bearing series, indicating a medium duty, single row deep groove ball bearing with 17mm bore, 47mm OD, and 14mm width. |
| 2RS | Contact rubber seals on both sides. Provides superior contamination exclusion and grease retention compared to shielded or open bearings. |
| JEM | Manufacturer-specific suffix indicating the use of a specific, high-quality pre-lubrication suitable for the stated temperature range. |
6303-2RSJEM Bearing Structural Features & Performance Benefits
- Robust Sealing: The double-sided rubber seals (2RS) effectively prevent the ingress of moisture, dust, and other contaminants, while also retaining the factory-applied lubricant. This results in a maintenance-free bearing solution for many applications.
- Radial Load Capacity: The deep groove raceway and single row design are optimized to handle significant radial dynamic loads (up to 3057 lbf) and radial static loads (up to 1495 lbf).
- Precision & Consistency: Manufactured to ABEC 1 | ISO P0 tolerance class with a CN radial internal clearance, ensuring smooth and quiet operation with minimal runout.
- Material Integrity: Constructed entirely from chrome steel (rings, balls, and cage), providing high hardness, wear resistance, and a long operational lifespan under standard conditions.
