1202 ETN9/C3 Bearing Product Overview & Core Advantages
The 1202 ETN9/C3 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 accommodate significant combined loads (both radial and axial) simultaneously. Its compact dimensions (15mm bore, 35mm OD, 11mm width) and robust construction make it ideal for space-constrained, high-performance assemblies. The bearing is characterized by its high rigidity and enhanced operational capabilities, supported by a nylon cage and a generous C3 radial internal clearance.
1202 ETN9/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| E | Optimized internal design | Enhanced load capacity and performance. |
| TN9 | Nylon (Polyamide) cage, pressed | Reduced friction, lower weight, and suitability for high-speed operation. |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in applications, preventing preload and ensuring stable operation. |
1202 ETN9/C3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball complement and robust construction provide superior high rigidity, enabling the bearing to handle significant radial loads and moderate axial loads from both directions effectively.
High-Speed Performance: The lightweight TN9 nylon cage minimizes centrifugal forces and friction, contributing directly to the bearing's high limiting speed of 28,000 rpm. The pre-applied lubrication ensures smooth operation from startup.
Precision & Reliability: Manufactured from chrome steel for both rings and balls, the bearing offers high dimensional stability and wear resistance. The specified C3 clearance provides operational stability across a wide temperature range (-30°C to 110°C).
