1222 KC3 Bearing Product Overview & Core Advantages
The 1222 KC3 is a double row angular contact ball bearing designed for demanding industrial applications requiring high load capacity and rigidity. Featuring a metric taper bore (1:12), this precision bearing excels at handling significant combined loads (radial and axial) simultaneously. Its double row design provides enhanced stability and stiffness, making it an ideal choice for machinery where shaft deflection must be minimized. Pre-lubricated and featuring a C3 radial internal clearance, it is engineered for reliable performance in applications with thermal expansion considerations.
1222 KC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1222 | Standard bearing designation indicating a double row angular contact ball bearing with a 110 mm bore and 200 mm outside diameter. |
| K | Denotes a taper bore with a 1:12 ratio, allowing for precise interference fit on tapered shafts for secure mounting. |
| C3 | Specifies a greater than normal radial internal clearance. This is critical for applications with expected thermal expansion, preventing preload and ensuring smooth operation. |
1222 KC3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design significantly increases the contact angle and number of load-carrying balls, resulting in superior stiffness and the ability to support substantial combined radial and axial loads.
- Optimized Cage & Speed: The nylon cage is lightweight, reduces friction, and contributes to the bearing's high limiting speed of 4,300 rpm, making it suitable for high-speed applications.
- Taper Bore Mounting: The 1:12 taper bore ensures a tight, slip-free fit on a tapered shaft, enhancing rotational accuracy and overall system stability.
- Pre-Lubricated & Ready-to-Use: Factory-applied lubrication simplifies installation and provides immediate protection, ensuring optimal performance from startup.
- Material Integrity: Constructed from high-grade chrome steel for both rings and balls, ensuring durability, long service life, and consistent performance under load.
