| K | Tapered bore (1:12) | Enables precise axial positioning and secure mounting on adapter sleeves |
| (No seal suffix) | Open construction | Allows for custom lubrication regimes and easier maintenance access |
1216 K Bearing Structural Features & Performance Benefits
High Radial Load Capacity: The double row design provides significantly higher radial load capacity compared to single row bearings, with a dynamic load rating of 8932 lbf and static load rating of 3825 lbf.
Precision Engineering: Manufactured with chrome steel rings and balls for superior durability and wear resistance. The nylon cage ensures smooth operation and reduced friction at the limiting speed of 6000 rpm.
Easy Installation: The tapered bore (K-suffix) facilitates precise mounting and dismounting using adapter sleeves, ensuring optimal alignment and high rigidity in the application.
Wide Temperature Range: Operates effectively in temperatures from -30°C to 110°C, making it suitable for various industrial environments.
