6202/C3W64 Bearing Product Overview & Core Advantages
The 6202/C3W64 is a single row deep groove ball bearing engineered for high-performance industrial applications. This precision bearing is characterized by its ability to accommodate significant radial loads and moderate axial loads in both directions. Manufactured to ABEC 1 | ISO P0 tolerance standards, it ensures reliable operation and consistent performance. A key feature is its Solid Oil lubrication system, which provides superior lubrication retention and is particularly advantageous in applications where re-lubrication is difficult or where contamination must be minimized. Its optimized internal geometry contributes to low noise and vibration levels, making it an ideal choice for demanding environments.
6202/C3W64 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in high-speed or high-temperature operations, reducing friction and preventing seizure. |
| W64 | Lubricated with Solid Oil | Offers a sealed-for-life, maintenance-free solution with excellent resistance to oil leakage and contamination, extending service life. |
6202/C3W64 Bearing Structural Features & Performance Benefits
Optimized Internal Geometry: The deep groove raceway and high-quality chrome steel construction provide excellent load carrying capacity and smooth operation.
Solid Oil Lubrication (W64): This polymer matrix saturated with oil replaces traditional grease, offering consistent lubrication, resistance to wash-out, and the ability to operate in a wider temperature range (-30° to 120 °C). This makes the bearing highly reliable and virtually maintenance-free.
Enhanced Radial Clearance (C3): The C3 internal clearance is specifically selected for applications with expected thermal expansion, ensuring stable performance and preventing premature failure in demanding conditions.
High-Speed Capability: With a limiting speed of 20,000 rpm, the combination of the open design, precision manufacturing, and effective Solid Oil lubrication enables reliable high-speed operation.
6202/C3W64 Bearing Typical Application Areas
- Electric Motors: Ideal for main shafts in small to medium-sized motors due to its high-speed capability and maintenance-free operation.
- Industrial Gearboxes: Provides reliable support for shafts under significant radial loads.
- Pumps and Compressors: The Solid Oil lubrication resists wash-out from coolants or other fluids, ensuring long service life.
- Material Handling Equipment: Conveyor rollers and pulleys benefit from its robust construction and high load capacity.
- Agricultural Machinery: Suited for harsh environments where contamination and the need for minimal maintenance are critical factors.
