1216KJC3 Bearing Product Overview & Core Advantages
The 1216KJC3 is a double row angular contact ball bearing designed for demanding applications requiring high rigidity and precision. This metric bearing features a tapered bore (1:12) for secure mounting on adapter sleeves or withdrawal sleeves. Its primary advantage lies in its ability to accommodate combined loads—significant radial loads—while maintaining high operational stability. The open design and optimized internal geometry contribute to its suitability for high-precision machinery where reliable performance is critical.
1216KJC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1216 | Standard bearing series designation, indicating the bearing dimensions (80mm bore, 140mm OD, 26mm width) |
| K | Indicates a tapered bore with a 1:12 ratio |
| JC3 | Specifies the radial internal clearance group C3 (greater than normal clearance) |
1216KJC3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball construction provides superior high rigidity, enabling the bearing to handle substantial radial loads with minimal deflection. This makes it ideal for applications with significant mechanical stress.
Optimized for Precision: Manufactured from chrome steel for both rings and balls, and featuring a steel cage, the bearing ensures consistent performance and durability. The specified C3 radial clearance accommodates thermal expansion in high-speed or high-temperature operations, preventing premature failure.
Speed & Temperature Performance: With a limiting speed of 6,000 rpm and an operational temperature range of -30°C to 110°C, this bearing is suitable for a variety of industrial environments. The open design allows for effective lubrication management, supporting high-speed operation when properly lubricated.
1216KJC3 Bearing Typical Application Areas
The 1216KJC3 is widely used in industrial machinery requiring robust performance and precision, including:
- Industrial Gearboxes and power transmission systems
- Material Handling Equipment such as conveyor pulleys
- Agricultural Machinery and heavy-duty implements
- Pump and Compressor assemblies
- Machinery with adapter sleeve mounting requirements
