1204-K C/3 Bearing Product Overview & Core Advantages
The 1204-K C/3 is a double row angular contact ball bearing designed for applications requiring high rigidity and precise operation. Featuring a 1:12 tapered bore for secure shaft mounting, this precision bearing excels at handling substantial combined loads (radial and axial) simultaneously. Its compact design, with optimized bearing dimensions (20mm bore, 47mm OD, 14mm width), makes it ideal for space-constrained, high-reliability machinery. The CN radial internal clearance and nylon cage contribute to smooth, quiet operation across its specified temperature range.
Model Code Breakdown
| Suffix Code | Technical Meaning |
|---|---|
| K | Indicates a 1:12 tapered bore for precise interference fit on tapered shafts, enhancing rotational accuracy. |
| C/3 | Specifies the CN radial internal clearance group, offering a standard, versatile clearance suitable for most general applications. |
1204-K C/3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing construction provides superior rigidity and enables the bearing to support significant combined radial and axial loads, making it suitable for demanding applications.
- Precision Tapered Bore: The 1:12 tapered bore (K-suffix) ensures a tight, secure fit on matching tapered shafts, minimizing inner ring creep and maintaining precise alignment for enhanced running accuracy.
- Optimized Cage Design: The lightweight, robust nylon cage ensures smooth ball guidance, reduces friction, and is suitable for high-speed operation up to the specified limiting speed.
- Standard Internal Clearance: The C3/CN clearance provides an optimal balance, accommodating moderate thermal expansion while maintaining precise operation under normal load and speed conditions.
- Material & Compliance: Manufactured from high-grade chrome steel for both rings and balls, ensuring durability and long service life. The bearing is compliant with ROHS and REACH regulations.
