1214 K/C3 Bearing Product Overview & Core Advantages
The 1214 K/C3 is a double row angular contact ball bearing designed for demanding applications requiring high rigidity and reliable performance under combined loads. Featuring a metric tapered bore (1:12 ratio), this precision bearing offers exceptional dimensional stability with tight tolerances. Its open design, pre-lubricated state, and specified C3 radial internal clearance make it suitable for applications with thermal expansion considerations, providing robust support in high-load environments.
1214 K/C3 Bearing Model Code Explained, Specifications & Naming Convention
- 1214: Basic bearing designation indicating bore diameter (70 mm) and dimensional series
- K: Denotes a tapered bore with a 1:12 ratio, facilitating secure mounting on adapter sleeves
- C3: Specifies a greater radial internal clearance than normal, suitable for applications with thermal expansion or where interference fits are used
1214 K/C3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row construction provides superior rigidity and enables the bearing to accommodate significant radial loads (dynamic: 8055 lbf, static: 3285 lbf) while managing some axial loads in both directions.
Precision Engineering: Manufactured from chrome steel for both rings and balls, with a nylon cage for reduced friction and smooth operation. The tapered bore ensures precise, secure mounting.
Optimized for Industrial Use: With a limiting speed of 7000 rpm and a temperature range of -30°C to 110°C, this bearing is built for continuous operation in challenging conditions. The C3 clearance accommodates thermal expansion, maintaining performance.
1214 K/C3 Bearing Typical Application Areas
The 1214 K/C3 is ideally suited for:
- Industrial Gearboxes and power transmission systems
- Material Handling Equipment such as conveyor pulleys
- Agricultural Machinery requiring robust bearing solutions
- Electric Motors and industrial fans
- Pump Systems operating under substantial radial loads
