1205 K Bearing Product Overview & Core Advantages
The 1205 K is a metric double row angular contact ball bearing featuring a tapered bore design (1:12 ratio) for precise mounting applications. This precision bearing is engineered to accommodate significant combined loads, including radial forces and axial loads in both directions, making it an ideal solution for applications demanding high rigidity and operational accuracy. Its compact design, with a 15 mm width, offers a space-saving solution without compromising performance. Manufactured from high-grade chrome steel and featuring a lightweight nylon cage, it is designed for reliable operation in demanding environments.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 1205 | Standard bearing designation indicating a metric double row angular contact ball bearing with a 25 mm bore diameter and 52 mm outside diameter. |
| K | Denotes a tapered bore with a 1:12 ratio. This design allows for precise axial positioning and secure mounting on adapter sleeves or withdrawal sleeves. |
1205 K Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides superior radial and axial stiffness, enabling the bearing to handle substantial combined loads effectively. This results in enhanced stability and reduced deflection in the supported shaft.
- Tapered Bore (K-designation): The 1:12 tapered bore facilitates precise interference fits when mounted with appropriate sleeves. This ensures a secure connection, minimizes fretting corrosion, and maintains accurate bearing alignment.
- Optimized for High-Speed Operation: The lightweight nylon cage reduces centrifugal forces, lowers friction, and contributes to a high limiting speed of 18,000 rpm, making it suitable for high-speed applications.
- Pre- lubricated & Ready for Use: The bearing is supplied pre-lubricated, ensuring immediate operational readiness and reducing initial setup time.
1205 K Bearing Typical Application Areas
This bearing is commonly specified in applications requiring high precision and rigidity, such as:
- Machine Tool Spindles
- Industrial Gearboxes
- Pumps and Compressors
- Electric Motors
- Precision Agricultural Machinery
