6312-RS2Z/C4S1VT228 Bearing Product Overview & Core Advantages
The 6312-RS2Z/C4S1VT228 is a single row deep groove ball bearing engineered for exceptional performance in demanding industrial applications. This metric bearing features a robust shielded design and is optimized to handle significant radial loads. Its key advantages include a high radial dynamic load rating of 18412 lbf, reliable operation across a wide temperature range from -30°C to 200°C, and compliance with RoHS and REACH standards, making it a versatile and dependable choice for high-reliability systems.
6312-RS2Z/C4S1VT228 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| RS2Z | Contact rubber seal on one side, non-contact steel shield on the other. | Provides effective contamination protection while offering a good balance between sealing and low friction. |
| C4 | Greater than normal radial internal clearance. | Ideal for applications with significant thermal expansion or where interference fits are used, preventing preload and ensuring smooth operation. |
| S1 | Stabilized heat treatment. | Enhances dimensional stability under fluctuating temperatures, contributing to consistent performance. |
| VT228 | Specific high-temperature lubricant. | Enables reliable operation across the specified wide temperature range (-30°C to 200°C). |
6312-RS2Z/C4S1VT228 Bearing Structural Features & Performance Benefits
The performance of the 6312-RS2Z/C4S1VT228 is derived from its precision construction. The single row deep groove raceway is designed for optimal radial load distribution. The combination of a chrome steel cage and high-grade chrome steel rings and balls ensures high strength and durability. The C4 radial clearance is a critical feature that accommodates thermal expansion in the system, preventing binding and reducing friction. The hybrid sealing with RS2Z effectively retains the VT228 lubricant and excludes contaminants, contributing to a long service life and maintenance-free operation in many environments. With an ABEC 1 | ISO P0 tolerance class, it offers reliable precision for a wide range of industrial machinery.
6312-RS2Z/C4S1VT228 Bearing Typical Application Areas
This bearing is well-suited for applications requiring robust performance under radial loads and in varied thermal conditions. Common uses include:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Material Handling Equipment (conveyors, pulleys)
- Agricultural Machinery
