6203-2RSH/C3W64 Bearing Product Overview & Core Advantages
The 6203-2RSH/C3W64 is a metric single row deep groove ball bearing engineered for superior performance in demanding applications. This sealed bearing excels at handling radial loads and moderate axial loads in both directions. Its key advantages include a robust sealed design for contamination protection, pre-lubrication with Solid Oil for long service life, and a C3 radial internal clearance suitable for applications with thermal expansion or heavy loads. This combination makes it an ideal, low-maintenance solution for a wide range of industrial machinery.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6203 | Standard bearing series; 17 mm bore, 40 mm OD, 12 mm width. |
| 2RSH | Contact seals on both sides. The "H" denotes a high-temperature resistant sealing material, offering superior exclusion of contaminants. |
| C3 | Radial internal clearance greater than Normal (CN). Ideal for applications with expected thermal expansion or where a heavy interference fit is used. |
| W64 | Designates the bearing is pre-lubricated with Solid Oil, a polymer matrix saturated with lubricant, providing excellent lifetime lubrication and resistance to wash-out. |
6203-2RSH/C3W64 Bearing Structural Features & Performance Benefits
Sealed and Pre-Lubricated Design: The 2RSH contact seals provide an effective barrier against dust, moisture, and other contaminants, significantly extending bearing life in harsh environments. Combined with Solid Oil (W64) lubrication, this bearing is effectively maintenance-free, eliminating the need for re-lubrication and preventing lubricant leakage.
Optimized Internal Geometry: The deep groove raceway and high-precision chrome steel construction enable smooth operation and efficient handling of radial dynamic loads up to 2147 lbf and radial static loads up to 1079 lbf.
Enhanced Operational Stability: The C3 clearance accommodates differential thermal expansion between the inner and outer rings, preventing pre-load and potential seizure in high-temperature or high-speed applications, contributing to reliable performance up to a limiting speed of 17,000 rpm.
6203-2RSH/C3W64 Bearing Typical Application Areas
- Electric Motors and Small Gearboxes
- Industrial Pumps and Fans
- Conveyor Systems and Material Handling Equipment
- Agricultural Machinery
- Automotive Components (e.g., alternators, idler pulleys)
- Food Processing and Packaging Machinery (where Solid Oil is advantageous)
