1219KC3 Bearing Product Overview & Core Advantages
The 1219KC3 is a double row angular contact ball bearing designed for demanding applications requiring high load capacity and precision. Featuring a tapered bore (1:12), this metric bearing excels at handling combined radial and axial loads simultaneously. Its double row construction provides superior rigidity and stability, making it ideal for high-precision machinery where reliable performance is critical. The bearing comes pre-lubricated and features a generous C3 radial internal clearance, suitable for applications with thermal expansion considerations.
1219KC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1219 | Standard bearing designation code |
| K | Indicates a tapered bore with a 1:12 ratio |
| C3 | Specifies a greater radial internal clearance than normal (C3 group) |
1219KC3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing design provides enhanced stiffness and can support significant combined radial and axial loads, with a dynamic load rating of 14,332 lbf and static load rating of 6,075 lbf.
- Precision Tapered Bore: The 1:12 taper enables precise bearing mounting and secure fit on adapter sleeves or tapered shafts, ensuring optimal alignment and load distribution.
- Optimized Internal Clearance: The C3 clearance accommodates thermal expansion in applications with higher operating temperatures or where interference fits are used, preventing premature failure.
- Durable Construction: Manufactured from chrome steel rings and balls with a stainless steel cage for corrosion resistance and reliable operation under demanding conditions.
- Pre-lubricated & Ready-to-Use: Factory lubricated for immediate installation, supporting a limiting speed of 5,000 rpm and operating within a temperature range of -30°C to 110°C.
1219KC3 Bearing Typical Application Areas
- Industrial Gearboxes and power transmission systems
- Vibrating Screens and material handling equipment
- Agricultural Machinery requiring high load capacity
- Pump Systems and industrial fans
- Construction Equipment with demanding operational environments
