1216K Bearing Product Overview & Core Advantages
The 1216K metric ball bearing is a double row angular contact ball bearing designed for exceptional performance in demanding applications. Featuring a 1:12 tapered bore for precise shaft mounting, this bearing is engineered to handle significant radial loads while offering high operational stability. Its double row construction provides superior rigidity and load-carrying capacity in a compact bearing size (80mm bore x 140mm OD x 26mm width). Manufactured from chrome steel with a nylon cage, it is optimized for smooth operation and is pre-lubricated for immediate use, making it an ideal precision bearing for high-reliability systems.
1216K Bearing Model Code Explained, Specifications & Naming Convention
- 1216: Basic designation indicating a double row angular contact ball bearing with tapered bore
- K: Denotes a tapered bore with a 1:12 taper ratio for secure mounting on adapter sleeves or withdrawal sleeves
1216K Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball bearing design provides enhanced stiffness and can accommodate substantial radial loads (dynamic: 8932 lbf, static: 3825 lbf), making it suitable for applications requiring robust support.
Precision Tapered Bore: The K-suffix tapered bore (1:12 taper) ensures precise interference fit when mounted with appropriate sleeves, eliminating clearance and providing secure shaft positioning.
Optimized Cage Design: The nylon cage contributes to smooth operation, reduced friction, and is suitable for the bearing's limiting speed of 6,000 rpm.
Material Excellence: Manufactured from chrome steel for both rings and balls, ensuring high durability, wear resistance, and consistent performance across the operating temperature range of -30°C to 110°C.
Standard Internal Clearance: The CN radial internal clearance provides optimal performance for most general applications under normal operating conditions.
1216K Bearing Typical Application Areas
The 1216K bearing is ideally suited for:
- Industrial gearboxes and transmission systems
- Material handling equipment including conveyors and pulleys
- Agricultural machinery requiring robust bearing solutions
- Electric motors and industrial fans
- Pump systems and compressor applications
- Machinery requiring precision mounting with tapered bore arrangements
