6311/C4S1VK176 Bearing Product Overview & Core Advantages
The 6311/C4S1VK176 is a single row deep groove ball bearing designed for robust performance in demanding applications. This open-type bearing is engineered to primarily handle high radial loads while also accommodating moderate axial loads in both directions. Its construction from high-grade chrome steel ensures durability and reliable operation. A key feature is its specified C4 radial internal clearance, making it particularly suitable for applications with anticipated thermal expansion or where interference fits are used. This bearing offers an excellent balance of high load capacity and operational reliability, making it a versatile component for industrial machinery.
6311/C4S1VK176 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6311 | Basic bearing designation: Metric series, single row deep groove ball bearing with 55mm bore, 120mm OD, 29mm width. |
| /C4 | Specifies a greater than normal radial internal clearance. Ideal for applications with shaft or housing interference fits, or where operational temperatures cause significant thermal expansion. |
| S1 | Indicates special heat stabilization treatment for the bearing rings, allowing for a stable temperature range up to 200°C. |
| VK176 | Manufacturer-specific code, often denoting a particular cage design (in this case, a pressed steel cage) and other proprietary manufacturing specifications. |
6311/C4S1VK176 Bearing Structural Features & Performance Benefits
- Optimized Internal Geometry: The deep groove raceway and precision-ground components enable efficient handling of both radial and axial loads, contributing to smooth operation and long service life.
- High-Temperature Stability: The S1 heat stabilization ensures dimensional stability and maintained performance across a wide operating temperature range from -30°C to 200°C.
- Enhanced Operational Flexibility: The C4 radial clearance provides greater internal space, reducing preload risks in high-temperature environments or where tight fits are required, thus preventing premature failure.
- Robust Construction: Manufactured entirely from chrome steel (rings, balls, and cage), this bearing delivers high strength, wear resistance, and consistent performance under the specified dynamic and static load ratings.
- Standard Precision: Conforms to ABEC 1 | ISO P0 tolerance class, offering reliable precision for a wide range of general industrial applications.
6311/C4S1VK176 Bearing Typical Application Areas
The 6311/C4S1VK176 is ideally suited for a variety of industrial sectors and equipment, including:
- Electric Motors and Generators: For supporting rotor shafts, especially in environments with variable thermal conditions.
- Industrial Gearboxes and Transmissions: Where high radial load capacity and thermal stability are critical.
- Material Handling Equipment: Such as conveyor pulleys and rollers.
- Agricultural Machinery: Including tractor components and harvesters.
- General Industrial Machinery: Pumps, fans, and blowers that operate within the bearing's specified temperature and speed limits.
