1217C3 Bearing Product Overview & Core Advantages
The 1217C3 is a double row angular contact ball bearing designed for demanding applications requiring high rigidity and reliable performance under combined loads. This precision bearing features an open design and is pre-lubricated, enabling it to handle significant radial loads while accommodating axial loads in both directions. Its compact bearing dimensions (85mm bore, 150mm OD, 28mm width) and C3 radial internal clearance make it an ideal choice for arrangements where moderate operational temperatures and shaft expansion are factors, ensuring stable operation in a wide temperature range from -30°C to 110°C.
1217C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1217 | Standard bearing series designation, indicating a metric double row angular contact ball bearing with an 85mm bore diameter and 150mm outside diameter. |
| C3 | Specifies a radial internal clearance greater than normal (C3 group). This is beneficial for applications with higher operational temperatures or where fits result in a reduction of internal clearance. |
1217C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and optimized raceway geometry provide high radial and moment stiffness, supporting a radial dynamic load rating of 10980 lbf and a radial static load rating of 4680 lbf. This construction is exceptionally capable of handling combined loads.
- Optimized for Performance: The bearing utilizes a stainless steel cage for strength and corrosion resistance, contributing to smooth operation at the limiting speed of 5,600 rpm. The open seal type allows for easy re-lubrication to maintain performance.
- Robust Material Construction: Manufactured from chrome steel for both rings and balls, ensuring high durability, wear resistance, and a long operational lifespan under strenuous conditions.
- Pre-lubricated & Ready for Service: The bearing comes pre-lubricated, facilitating immediate installation and initial operation, reducing setup time and complexity.
1217C3 Bearing Typical Application Areas
The 1217C3 bearing is engineered for a diverse range of industrial machinery and equipment, including:
- Industrial Gearboxes and Transmissions
- Medium-Duty Pump and Compressor Systems
- Material Handling Conveyors
- Agricultural and Construction Machinery
- Electric Motors and Generators
