1217 KC3 Bearing Product Overview & Core Advantages
The 1217 KC3 is a metric double row angular contact ball bearing engineered for applications requiring high rigidity and the ability to handle combined loads. Featuring a tapered bore design (1:12) and C3 radial internal clearance, this precision bearing is optimized for demanding industrial environments where reliable performance under significant radial forces is essential. Its compact bearing dimensions (85 mm bore, 150 mm OD, 28 mm width) and robust construction make it an ideal solution for high-precision machinery.
1217 KC3 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| K | Tapered Bore (1:12) | Enables precise mounting and adjustment on tapered shafts |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in high-temperature applications |
1217 KC3 Bearing Structural Features & Performance Benefits
Double Row Design: The double row angular contact ball bearing configuration provides high rigidity and superior load distribution, making it capable of handling substantial radial loads (dynamic: 10,980 lbf / static: 4,680 lbf).
Precision Components: Constructed with chrome steel rings and balls combined with a nylon cage, this bearing ensures smooth operation and reduced friction. The optimized internal geometry contributes to its limiting speed of 5,600 rpm.
Tapered Bore Advantage: The 1:12 tapered bore allows for precise axial positioning and secure mounting on matching tapered shafts, enhancing overall system stability and alignment accuracy.
Operating Versatility: With a temperature range of -30°C to 110°C and factory lubrication, the bearing is ready for immediate installation in various industrial environments.
1217 KC3 Bearing Typical Application Areas
- Industrial Gearboxes and power transmission systems
- Material Handling Equipment including conveyor systems
- Agricultural Machinery requiring robust bearing solutions
- Industrial Fans and Blowers operating at moderate speeds
- Construction Equipment where high radial load capacity is critical
