1205 C3 Bearing Product Overview & Core Advantages
The 1205 C3 is a double row angular contact ball bearing designed for applications requiring high radial load capacity and robust performance. This metric bearing features an open design without seals, allowing for optimal lubrication access and heat dissipation. Its construction enables it to handle significant radial loads while maintaining operational stability. With a C3 radial internal clearance, it is specifically engineered for applications where thermal expansion or fit-induced preload is a consideration, ensuring reliable performance under varying operational conditions. The combination of chrome steel rings, chrome steel balls, and a nylon cage delivers a balance of durability, smooth operation, and reduced weight.
1205 C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1205 | Basic bearing designation. 12 indicates a light series with a 25mm bore diameter. 05 indicates a 52mm outside diameter and 15mm width. |
| C3 | Specifies a greater than normal radial internal clearance. This is critical for applications with expected thermal expansion, interference fits, or where lower operational temperatures are required. |
1205 C3 Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The double row ball bearing construction provides superior radial load support and high rigidity, making it suitable for applications with significant mechanical stresses.
- Optimized Internal Clearance: The C3 clearance is a key performance feature, accommodating shaft and housing fits while preventing excessive preload that can lead to overheating and premature failure.
- High-Speed Capability: The lightweight nylon cage ensures stable ball guidance and reduces centrifugal forces, contributing to a high limiting speed of 18,000 rpm.
- Material Durability: Components made from chrome steel offer excellent wear resistance and fatigue life, ensuring long-term reliability in demanding environments.
- Precision Tolerances: Tight dimensional tolerances on the bore, outside diameter, and width guarantee precise fitment and consistent performance in high-precision assemblies.
1205 C3 Bearing Typical Application Areas
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Systems (conveyors, rollers)
