1205T2C4 Bearing Product Overview & Core Advantages
The 1205T2C4 is a double row angular contact ball bearing designed for applications requiring high precision and reliability. This metric bearing features an open design and is pre-lubricated, enabling it to handle significant combined loads—both radial and axial forces—simultaneously. Its compact bearing dimensions (25mm bore, 52mm OD, 15mm width) and robust construction make it ideal for space-constrained, high-performance machinery. The optimized internal geometry and C4 radial clearance contribute to stable operation under varying thermal conditions, ensuring consistent performance in demanding environments.
1205T2C4 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1205 | Standard bearing designation indicating a 25mm bore diameter and 52mm outside diameter |
| T2 | Nylon cage construction for reduced weight and smooth operation at high speeds |
| C4 | Greater than normal radial internal clearance for applications with significant thermal expansion |
1205T2C4 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior rigidity compared to single row bearings, enabling stable support for combined loads. With a dynamic load rating of 3218 lbf and static load rating of 900 lbf, this bearing delivers reliable performance under substantial mechanical stress.
Optimized High-Speed Performance: The nylon cage (T2) reduces rotational mass and friction, contributing to smooth operation at speeds up to 18,000 rpm. The open construction allows for efficient lubrication management in high-speed applications.
Precision Engineering: Manufactured from chrome steel for both rings and balls, this bearing ensures dimensional stability and extended service life. The tight dimensional tolerances (bore: -0.01mm to 0, OD: -0.013mm to 0) guarantee precise fitment and consistent performance.
Thermal Adaptation: The C4 radial clearance accommodates thermal expansion in applications where operating temperatures vary, preventing premature failure due to excessive preload.
1205T2C4 Bearing Typical Application Areas
- Electric Motors & Generators: Ideal for main shaft support in small to medium-sized motors requiring high-speed capability and thermal stability
- Industrial Gearboxes: Provides reliable power transmission in compact gear reduction units
- Material Handling Equipment: Suitable for conveyor systems and automated guided vehicles
- Agricultural Machinery: Used in implement drives and PTO shafts where combined loads are prevalent
- Industrial Fans & Blowers: Supports high-speed rotor assemblies with minimal maintenance requirements
