1305 ETN9/W64 Bearing Product Overview & Core Advantages
The 1305 ETN9/W64 is a metric double row angular contact ball bearing engineered for applications requiring high rigidity and precise operation. This precision bearing features an open design and is pre-lubricated, enabling it to handle significant combined loads (radial and axial) simultaneously. Its compact bearing dimensions (25mm bore, 62mm OD, 17mm width) make it ideal for space-constrained, high-reliability applications where consistent performance is critical.
1305 ETN9/W64 Bearing Model Code Explained, Specifications & Naming Convention
- 1305: Basic designation indicating 25mm bore diameter and medium cross-section
- E: Optimized internal design for enhanced load capacity
- TN9: Nylon cage (Polyamide 66), providing excellent high-speed performance and reduced friction
- W64: Special pre-lubrication with high-quality grease suitable for the specified temperature range
1305 ETN9/W64 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row construction provides superior rigidity and enables the bearing to handle substantial combined radial and axial loads, making it suitable for applications with complex loading conditions.
High-Speed Performance: The TN9 nylon cage ensures smooth operation at high rotational speeds (limiting speed: 15,000 rpm) while reducing vibration and noise levels.
Pre-Lubricated & Maintenance-Friendly: Factory-applied W64 grease lubrication provides long-term performance across the operating temperature range (-30°C to 110°C), reducing maintenance requirements.
Precision Engineering: Manufactured from chrome steel with tight dimensional tolerances, ensuring consistent performance and extended service life in demanding applications.
