1204 EKTN9 Bearing Product Overview & Core Advantages
The 1204 EKTN9 is a double row angular contact ball bearing designed for applications requiring high precision and reliability. This precision bearing features an open design and is pre-lubricated, enabling it to accommodate combined loads—significant radial loads and moderate axial loads in both directions. Its compact bearing dimensions (20mm bore, 47mm OD, 14mm width) and robust construction make it an ideal solution for space-constrained, high-performance mechanical systems demanding high rigidity and stable operation.

|---|---|
| EK | Optimized internal design with reinforced ribs and contact angle for enhanced load capacity |
| TN9 | Nylon cage, glass fiber reinforced, suitable for high-speed applications |
1204 EKTN9 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and optimized contact angle provide superior high rigidity, enabling the bearing to handle substantial combined loads (radial dynamic load rating: 2858 lbf).
- High-Speed Performance: The TN9 nylon cage reduces centrifugal forces and friction, contributing to an exceptional limiting speed of 20,000 rpm, making it a true high-speed bearing.
- Precision & Stability: Manufactured with tight dimensional tolerances (bore: -0.01mm to 0) from chrome steel, ensuring precise running accuracy and minimal vibration.
- Pre-Lubricated & Ready-to-Use: Factory-applied lubrication allows for immediate installation and reliable initial operation within a wide temperature range (-30°C to 110°C).
