1217 K/C3 Bearing Product Overview & Core Advantages
The 1217 K/C3 is a double row angular contact ball bearing designed for demanding applications requiring high rigidity and reliable performance under combined loads. Featuring a tapered bore (1:12) for precise shaft mounting, this precision bearing offers excellent radial load capacity while accommodating axial loads in both directions. Its compact design with optimized bearing dimensions (85mm bore, 150mm OD, 28mm width) makes it ideal for space-constrained, high-performance machinery. The C3 radial internal clearance ensures optimal operation under varying thermal conditions.
1217 K/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1217 | Standard bearing designation (85mm bore, 150mm OD) |
| K | Tapered bore with 1:12 ratio for precise mounting and adjustment |
| C3 | Greater radial internal clearance for thermal expansion in high-speed applications |
1217 K/C3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior stiffness and enables the bearing to handle significant combined radial and axial loads simultaneously, making it suitable for applications with complex loading conditions.
Precision Engineering: Manufactured from chrome steel for both rings and balls, ensuring durability and consistent performance. The nylon cage contributes to smooth operation and reduced friction at high speeds.
Optimized Thermal Performance: The C3 clearance accommodates differential thermal expansion between bearing components and housing, preventing preload issues and maintaining performance across the operating temperature range (-30° to 110°C).
Enhanced Mounting Precision: The tapered bore allows for precise axial positioning and secure mounting on adapter sleeves or tapered shafts, ensuring optimal alignment and load distribution.
