1202 ETN9 Bearing Product Overview & Core Advantages
The 1202 ETN9 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 radial loads while maintaining stable operation. Its compact dimensions (15mm bore, 35mm OD, 11mm width) and high rigidity make it ideal for space-constrained, high-performance mechanical systems. The bearing is manufactured from chrome steel for durability and complies with ROHS and REACH standards.
1202 ETN9 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Advantage |
|---|---|---|
| E | Optimized internal design | Enhanced load capacity and performance |
| TN9 | Nylon (polyamide) cage, glass fiber reinforced | Reduced friction, suitable for high-speed applications up to 28,000 rpm |
1202 ETN9 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball construction provides superior rigidity and enables the bearing to support substantial radial dynamic loads (1667 lbf). This design is engineered for stability under demanding operating conditions.
High-Speed Performance: The lightweight TN9 nylon cage minimizes centrifugal forces and friction, contributing to a high limiting speed of 28,000 rpm. This makes the 1202 ETN9 an excellent high-speed bearing.
Precision & Reliability: Manufactured with tight dimensional tolerances (bore: -0.008mm to 0) and high-grade chrome steel components, this bearing ensures consistent performance and long service life in precision machinery.
Pre-Lubricated & Ready-to-Use: The bearing comes lubricated from the factory, simplifying installation and providing immediate protection, suitable for an operating temperature range of -30°C to 110°C.
