1214 K Bearing Product Overview & Core Advantages
The 1214 K is a metric double row angular contact ball bearing designed for exceptional performance in demanding applications. Featuring a tapered bore (1:12) and open construction, this bearing delivers high rigidity and precise operation. Its double row design enables it to accommodate combined loads—significant radial forces along with axial loads in both directions—making it ideal for applications requiring superior stability and accuracy. Manufactured with precision tolerances and nylon cage construction, the 1214 K ensures reliable performance in high-speed and precision machinery.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 1214 | Standard bearing designation indicating metric dimensions (70mm bore, 125mm OD, 24mm width) |
| K | Tapered bore with 1:12 taper ratio for precise mounting and positioning on tapered shafts |
1214 K Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact design provides enhanced stiffness and superior load distribution, enabling the bearing to handle combined radial and axial loads simultaneously. With a dynamic load rating of 8055 lbf and static load rating of 3285 lbf, it offers reliable performance under substantial operating stresses.
Precision Engineering: Manufactured with chrome steel rings and balls for durability and wear resistance. The nylon cage ensures smooth operation at high speeds (limiting speed: 7000 rpm) while reducing friction and heat generation.
Tapered Bore Advantage: The 1:12 tapered bore facilitates precise mounting and dismounting on adapter sleeves or tapered shafts, ensuring optimal fit and minimizing internal clearance variations.
Optimized Internal Clearance: Standard CN radial internal clearance provides balanced performance for most industrial applications, accommodating thermal expansion while maintaining operational precision.
