1205KTNC3 Bearing Product Overview & Core Advantages
The 1205KTNC3 is a metric double row angular contact ball bearing engineered for applications requiring high precision and reliability. Featuring a tapered bore (1:12) and C3 radial internal clearance, this bearing delivers exceptional performance in handling combined radial and axial loads. Its compact design with a 15mm width provides space-saving advantages while maintaining high rigidity and stable operation under demanding conditions. Pre-lubricated and constructed with chrome steel components, it offers reliable service in various industrial environments.
Model Code Detailed Explanation
| Code Segment | Technical Meaning |
|---|---|
| 1205 | Basic designation: 25mm bore diameter, 52mm outside diameter |
| K | Tapered bore with 1:12 ratio |
| TN | Nylon cage (injection molded) |
| C3 | Greater than normal radial internal clearance |
1205KTNC3 Bearing Structural Features & Performance Benefits
Double Row Design: The two rows of balls provide enhanced load capacity and superior rigidity compared to single row bearings, making it ideal for applications with significant radial and axial load combinations.
Tapered Bore: The 1:12 tapered bore allows for precise bearing adjustment and secure mounting on adapter sleeves or withdrawal sleeves, ensuring optimal fit and performance.
Nylon Cage (TN): The injection-molded nylon cage offers reduced friction, excellent high-speed capability, and corrosion resistance, contributing to the bearing's limiting speed of 18,000 rpm.
C3 Clearance: The increased radial internal clearance accommodates thermal expansion in applications with elevated operating temperatures or where interference fits are used.
Pre-lubricated: Factory-applied lubrication ensures immediate operation and reduces maintenance requirements during initial service periods.
