| J | Steel Cage with Machined Pockets | Provides excellent guidance and stability at high speeds |
1214KJ Bearing Structural Features & Performance Benefits
- High Rigidity Design: The double row angular contact configuration with tapered bore creates an exceptionally stiff bearing system capable of resisting deflection under heavy radial loads
- Superior Load Capacity: Engineered to handle significant radial dynamic loads (8055 lbf) while maintaining stable operation, making it suitable for applications with substantial combined loading conditions
- Optimized Internal Geometry: Precision-ground raceways and controlled radial internal clearance (CN) ensure smooth operation and extended service life
- Premium Material Construction: Chrome steel rings and balls combined with a steel cage provide excellent wear resistance and dimensional stability
- Pre-lubricated Performance: Factory-applied lubrication ensures immediate operation and reliable performance across the specified temperature range
1214KJ Bearing Typical Application Areas
- Industrial Gearboxes and power transmission systems requiring high radial load capacity
- Machine Tool Spindles and precision rotating equipment demanding exceptional rigidity
- Material Handling Equipment such as conveyor systems and industrial rollers
- Agricultural Machinery including tractor transmissions and harvesting equipment
- Pump and Compressor Systems where reliable bearing performance is critical
- Electric Motor Applications requiring stable operation under radial loading conditions
