1214K Bearing Product Overview & Core Advantages
The 1214K metric double row angular contact ball bearing represents a precision bearing solution engineered for applications demanding high rigidity and reliable performance under combined loads. Its double row design enables it to simultaneously support significant radial loads and bidirectional axial loads, making it exceptionally compact and space-efficient. Manufactured with chrome steel rings and balls, and featuring a nylon cage, this bearing is optimized for smooth operation and is pre-lubricated for immediate use, delivering high reliability in demanding industrial environments.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 1214 | Standard bore diameter code (70 mm) and series designation |
| K | Tapered bore with 1:12 ratio for secure shaft mounting |
| Open | No contact seals, enabling higher speed operation |
| CN | Standard radial internal clearance for general applications |
1214K Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact construction provides superior stiffness, effectively handling combined radial and axial loads from both directions. With a dynamic load rating of 8055 lbf and static rating of 3285 lbf, it offers robust performance in demanding conditions.
Optimized High-Speed Performance: The lightweight nylon cage reduces centrifugal forces, contributing to a limiting speed of 7,000 rpm. The open design minimizes friction and heat generation, making it suitable for high-speed applications.
Precision Tapered Bore: The K-suffix tapered bore (1:12) ensures precise interference fit on tapered shafts, eliminating creep and maintaining positional accuracy under heavy loads and high speeds.
Ready-to-Install Convenience: Pre-lubricated and featuring standard CN clearance, the bearing is immediately operational upon installation within its specified temperature range of -30° to 110°C.
1214K Bearing Typical Application Areas
- Industrial Gearboxes and power transmission systems
- Machine Tool Spindles requiring high precision and rigidity
