1205-K C/3 Bearing Product Overview & Core Advantages
The 1205-K C/3 is a double row angular contact ball bearing designed for applications requiring high precision and rigid support. This metric bearing features a tapered bore (1:12) for secure shaft mounting and exceptional stability. Engineered to handle significant radial loads, it offers a compact design with a 15 mm width, making it ideal for space-constrained, high-performance machinery. The bearing comes pre-lubricated and operates effectively within a temperature range of -30°C to 110°C, ensuring reliability in demanding industrial environments.
1205-K C/3 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| K | Indicates a tapered bore with a 1:12 ratio, facilitating precise interference fits on tapered shafts for enhanced rigidity. |
| C/3 | Specifies the radial internal clearance group. C3 denotes a clearance greater than normal (CN), suitable for applications with expected thermal expansion or where a tighter fit is used. |
1205-K C/3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing construction provides superior stiffness and enables the bearing to support substantial radial dynamic loads (rated at 3218 lbf), making it suitable for applications with significant operational forces.
- Precision Tapered Bore: The 1:12 tapered bore ensures a secure, concentric fit on the shaft, minimizing slippage and maintaining high running accuracy.
- Optimized Cage & Speed: The nylon cage contributes to smooth operation, low friction, and allows for a high limiting speed of 18,000 rpm, qualifying it as a high-speed bearing.
- Ready-to-Install & Durable: The bearing is supplied lubricated and features an open design, ready for immediate use in systems with controlled environments. Manufactured from chrome steel, it ensures long-term durability and performance.
1205-K C/3 Bearing Typical Application Areas
This double row angular contact ball bearing is ideally suited for:
- Machine Tool Spindles
- Industrial Gearboxes
- Pumps and Compressors
- Precision Agricultural Machinery
- Material Handling Equipment
