1305 KC3 Bearing Product Overview & Core Advantages
The 1305 KC3 is a double row angular contact ball bearing designed for applications requiring high rigidity and reliable performance under combined loads. Featuring a metric taper bore (1:12), this precision bearing excels in handling significant radial loads while offering simplified mounting on tapered shafts. Its open design, pre-lubricated state, and C3 radial internal clearance make it suitable for applications with thermal expansion or demanding operational conditions, providing a robust solution for industrial machinery.
1305 KC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1305 | Standard bearing series designation, indicating core dimensions (25mm bore, 62mm OD). |
| K | Denotes a metric taper bore with a 1:12 ratio, facilitating secure mounting and dismounting on tapered shafts. |
| C3 | Indicates a greater than normal radial internal clearance. This is beneficial for applications involving thermal expansion, high speeds, or where fits create a reduction in clearance. |
1305 KC3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball construction provides superior radial stiffness and enables the bearing to support substantial combined loads, making it ideal for applications with significant radial forces.
- Precision Taper Bore: The 1:12 taper bore ensures a tight, interference fit on a matching shaft, eliminating creep and improving rotational accuracy. This design also simplifies installation and removal.
- Optimized Cage & Lubrication: The Nylon cage contributes to smooth operation, lower friction, and is suitable for high-speed applications. The bearing is pre-lubricated, ensuring immediate operational readiness.
- Wide Operating Range: With a temperature range of -30°C to 110°C and a limiting speed of 15,000 rpm, this bearing offers reliable performance across diverse operating conditions.
1305 KC3 Bearing Typical Application Areas
The 1305 KC3 is engineered for demanding industrial environments. Its key applications include:
- Electric Motors and Gearboxes
- Agricultural Machinery
- Material Handling Equipment (e.g., conveyor pulleys)
- Industrial Fans and Blowers
- Machinery with tapered shaft interfaces
