6003-RS1TN9/C4 Bearing Product Overview & Core Advantages
The 6003-RS1TN9/C4 is a single row deep groove ball bearing engineered for high performance and reliability in demanding applications. This sealed bearing is designed to primarily handle radial loads while also accommodating moderate axial loads in both directions. Its compact design, featuring a 17 mm bore, 35 mm outside diameter, and 10 mm width, makes it an ideal solution for space-constrained assemblies. Manufactured to ABEC 1 | ISO P0 tolerance standards, it ensures consistent operation and is pre-lubricated for immediate use, offering a robust combination of precision and durability.
6003-RS1TN9/C4 Bearing Model Code Explained, Specifications & Naming Convention
| 6003 | Basic bearing series, indicating a 17mm bore and 35mm outside diameter. |
| RS1 | Designates a contact rubber seal on one side of the bearing, providing effective protection against contaminants. |
| TN9 | Indicates a glass fiber reinforced nylon cage (PA66), which contributes to low friction, quiet operation, and is suitable for high-speed applications. |
| C4 | Specifies a greater than normal radial internal clearance. This is beneficial for applications with significant thermal expansion or where interference fits are used. |
6003-RS1TN9/C4 Bearing Structural Features & Performance Benefits
Optimized Load Capacity: The single row deep groove raceway geometry is precision-engineered to efficiently support high radial dynamic load ratings of 1349 lbf, ensuring reliable performance under significant stress.
Enhanced Contamination Protection: The integral RS1 contact seal effectively shields the internal components from dust, moisture, and other contaminants, significantly extending the bearing's service life and reliability.
High-Speed Capability: The lightweight TN9 nylon cage minimizes centrifugal forces, reduces friction, and allows for a high limiting speed of 21,000 rpm, making it suitable for demanding rotational applications.
Thermal Stability: The specified C4 radial internal clearance accommodates thermal expansion in the shaft and housing, preventing preload and potential seizure in applications with elevated operating temperatures.
6003-RS1TN9/C4 Bearing Typical Application Areas
