6203-2RSHNR Bearing Product Overview & Core Advantages
The 6203-2RSHNR is a single row deep groove ball bearing engineered for reliable performance in demanding applications. Its sealed design and integrated snap ring provide exceptional protection and simplified mounting. This bearing is characterized by its ability to handle primarily radial loads and is manufactured to ABEC 1 | ISO P0 tolerance standards, ensuring consistent quality and smooth operation. The combination of robust construction and effective sealing makes it an ideal, cost-effective solution for a wide range of industrial machinery.
Model Code Breakdown
- 6203: Standard designation for a single row deep groove ball bearing with a 17mm bore, 40mm OD, and 12mm width.
- 2RS: Indicates that the bearing is fitted with contact seals on both sides. These seals effectively retain lubricant and exclude contaminants.
- H: This suffix denotes that the bearing's internal radial clearance is tighter than the standard CN group.
- NR: Signifies that the bearing's outer ring has a snap ring groove and a snap ring is fitted. This feature allows for simplified axial location within a housing.
6203-2RSHNR Bearing Structural Features & Performance Benefits
Sealed for Protection and Longevity: The double-sided contact seals (2RS) provide excellent defense against contamination and moisture, while also retaining the lubricant. This design contributes to a maintenance-free service life in many applications.
Secure Axial Location: The integrated snap ring (NR) on the outer ring simplifies assembly by providing a positive axial locating surface, reducing the need for complex housing designs and machining.
Optimized Internal Clearance: The reduced internal clearance (H) is beneficial for applications requiring precise shaft guidance and reduced noise and vibration levels.
Robust Load Capacity: Constructed from chrome steel for both rings and balls, this bearing offers a high dynamic load rating of 2147 lbf and a static load rating of 1079 lbf, ensuring durability under significant radial stresses.
6203-2RSHNR Bearing Typical Application Areas
The 6203-2RSHNR is widely used across various industries due to its sealed and pre-lubricated design. Common applications include:
- Electric Motors and Gearboxes
- Industrial Fans and Blowers
- Conveyor Systems
- Agricultural Machinery
- Material Handling Equipment
