2205 K Bearing Product Overview & Core Advantages
The 2205 K is a metric double row angular contact ball bearing designed for applications requiring high rigidity and precise operation. This sealed bearing features a tapered bore (1:12) for secure shaft mounting and is pre-lubricated for long-term performance. Its double row design enables it to support significant combined loads (radial and axial) simultaneously, making it an ideal choice for compact, high-reliability assemblies where space is at a premium and operational stability is critical.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 2205 | Standard bore diameter (25 mm) and series designation. |
| K | Indicates a tapered bore with a 1:12 ratio, facilitating precise axial positioning and interference fit on the shaft. |
2205 K Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing construction provides superior stiffness, effectively handling substantial radial loads and bidirectional axial loads. This makes it exceptionally stable under combined loading conditions.
- Precision & Reliability: Manufactured from chrome steel for both rings and balls, the bearing ensures high durability and consistent performance. The standard CN radial internal clearance is suited for a wide range of general applications.
- Maintenance-Free Operation: The integral seals protect against contamination and retain the factory-applied lubricant, enabling extended service life without re-lubrication in many environments.
- Optimized Design: The lightweight nylon cage contributes to smooth operation at the specified limiting speed of 9,000 rpm, reducing friction and heat generation.
2205 K Bearing Typical Application Areas
This bearing is commonly specified in:
- Electric Motors and Gearboxes
- Light to Medium-duty Industrial Pumps and Compressors
- Material Handling Equipment (e.g., conveyor pulleys)
- Various Agricultural Machinery components
- Precision Mechanical Drives requiring a secure tapered bore fit
