1224 KM/C3 Bearing Product Overview & Core Advantages
The 1224 KM/C3 is a double row angular contact ball bearing designed for demanding industrial applications requiring high load capacity and rigidity. This metric bearing features a tapered bore (1:12) for precise interference fits on adapter sleeves or withdrawal sleeves, ensuring secure mounting on shafts. Its double row design enables it to support significant combined loads—both radial and axial forces—simultaneously, making it an ideal choice for applications where high precision and operational reliability are paramount. The bearing is pre-lubricated and features an open design with a C3 radial internal clearance, optimized for applications with thermal expansion or heavy loads.
1224 KM/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1224 | Standard bearing designation indicating bore diameter (120 mm) and series. |
| KM | Tapered bore designation (1:12), suitable for mounting with adapter sleeves. |
| C3 | Radial internal clearance greater than normal, suitable for applications with thermal expansion or heavy interference fits. |
1224 KM/C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing construction provides superior rigidity and can handle high radial dynamic load ratings (26,775 lbf) and static load ratings (11,925 lbf), making it suitable for heavy-duty applications.
- Optimized for Combined Loads: Engineered to accommodate combined radial and axial loads simultaneously, ensuring stable performance in complex load conditions.
- Precision Tapered Bore: The KM-designated tapered bore allows for precise axial positioning and secure mounting, reducing slippage under high torque.
- Durable Material Construction: Manufactured from chrome steel rings and balls with a brass cage, offering excellent wear resistance and durability under high-speed conditions (limiting speed: 4,000 rpm).
- Wide Operating Range: Operates effectively within a temperature range of -30°C to 110°C, with pre-applied lubrication for immediate use.
