1218KC3 Bearing Product Overview & Core Advantages
The 1218KC3 is a double row angular contact ball bearing designed for applications requiring high radial load capacity and precise operation. Featuring a metric system and tapered bore (1:12), it ensures secure mounting on tapered shafts. Its open seal type allows for optimal lubrication access, while the C3 radial internal clearance accommodates thermal expansion in demanding environments. This bearing is engineered for high rigidity and reliable performance in industrial machinery.

| 1218 | Standard bearing series designation |
| K | Tapered bore with 1:12 ratio |
| C3 | Greater than normal radial internal clearance |
1218KC3 Bearing Structural Features & Performance Benefits
Double Row Design: Provides enhanced radial load capacity and high rigidity compared to single row bearings, making it suitable for applications with significant radial forces.
Precision Components: Manufactured from chrome steel rings and balls with stainless steel cage for durability and corrosion resistance in demanding environments.
Tapered Bore Advantage: The 1:12 taper ensures secure interference fit on matching shafts, preventing creep and maintaining precise alignment under heavy loads.
Optimized Performance: With a radial dynamic load rating of 12,870 lbf and limiting speed of 5,300 rpm, this bearing delivers reliable operation in high-performance applications.
1218KC3 Bearing Typical Application Areas
- Industrial Gearboxes and power transmission systems
- Material Handling Equipment including conveyor systems
- Agricultural Machinery requiring heavy-duty radial load support
- Industrial Fans and Blowers operating at moderate speeds
- Construction Equipment components subject to significant radial forces
