6203/C3VB243 Bearing Product Overview & Core Advantages
The 6203/C3VB243 is a single row deep groove ball bearing designed for reliable performance in demanding applications. This metric bearing excels at handling radial loads while also accommodating moderate axial loads in both directions. Its open design allows for versatile lubrication options, and the C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or where interference fits are used. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers a robust balance of precision, durability, and cost-effectiveness for general industrial use.
6203/C3VB243 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6203 | Standard designation for a single row deep groove ball bearing with a 17mm bore, 40mm OD, and 12mm width. |
| /C3 | Indicates a greater than normal radial internal clearance. This is beneficial in applications with elevated operating temperatures or where shaft fits create a reduction in clearance. |
| /VB243 | This is a manufacturer-specific suffix. It typically denotes a specific cage design and material (in this case, a pressed steel cage, as indicated by the "Chrome Steel" cage material in the specifications). |
6203/C3VB243 Bearing Structural Features & Performance Benefits
- Robust Construction for High Load Capacity: Built entirely from chrome steel for the rings, balls, and cage, this bearing provides a high dynamic load rating of 2147 lbf and a static load rating of 1079 lbf, ensuring reliable operation under significant radial loads.
- Optimized for Versatile Applications: The open seal type allows for easy re-lubrication and custom lubrication schemes to suit specific operational needs, including high-speed environments with a limiting speed of 17,000 rpm.
- Accommodates Thermal and Fit Conditions: The C3 radial internal clearance is a key feature that helps prevent binding and excessive preload in applications prone to thermal expansion or where tight shaft fits are employed.
- Standardized Precision: Conformance to ABEC 1 | ISO P0 tolerance class guarantees consistent dimensional accuracy and smooth running performance, making it a dependable choice for a wide range of machinery.
