1216 KC3 Bearing Product Overview & Core Advantages
The 1216 KC3 is a double row angular contact ball bearing designed for demanding applications requiring high rigidity and the ability to handle combined loads. Its metric design features a tapered bore (1:12) for precise shaft mounting and secure interference fits. This bearing is engineered to support significant radial loads while offering robust performance. Manufactured from high-grade chrome steel and featuring a lightweight nylon cage, it is pre-lubricated for immediate use and is characterized by its compact cross-section, making it an ideal choice for high-reliability and precision machinery.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 1216 | Standard bearing designation indicating the bearing size (80 mm bore, 140 mm OD, 26 mm width). |
| K | Denotes a tapered bore with a 1:12 ratio, facilitating precise mounting and dismounting on adapter sleeves or withdrawal sleeves. |
| C3 | Specifies a greater than normal radial internal clearance. This is beneficial for applications with thermal expansion or where interference fits are used. |
1216 KC3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement provides superior high rigidity and enables the bearing to accommodate substantial combined loads (radial and axial).
- Precision Tapered Bore: The 1:12 tapered bore ensures a secure, concentric fit on the shaft, minimizing slippage and vibration under heavy loads.
- Optimized Cage Design: The standard nylon cage offers excellent performance in high-speed applications, contributing to lower friction and a higher limiting speed.
- Pre-Lubricated & Ready-to-Use: The bearing comes pre-lubricated, ensuring immediate operational readiness and protection during the initial run-in period.
- Wide Operating Range: With a temperature range from -30°C to 110°C, it is suitable for a variety of industrial environments.
1216 KC3 Bearing Typical Application Areas
This double row angular contact ball bearing is ideally suited for applications requiring robust performance and high precision, including:
- Industrial Gearboxes and Transmissions
- Vibrating Screens and Conveyors
- Agricultural Machinery
- Pump and Compressor Systems
- Material Handling Equipment
