1210 ETN9/W64 Bearing Product Overview & Core Advantages
The 1210 ETN9/W64 is a double row angular contact ball bearing designed for applications requiring high precision and robust performance. This precision bearing excels at simultaneously handling combined loads, including significant radial loads and moderate axial loads in both directions. Its compact design, characterized by a bearing size of 50 mm bore and 90 mm outside diameter, makes it ideal for space-constrained, high-reliability applications. The optimized internal geometry and material selection contribute to its high rigidity and stable operation.
1210 ETN9/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1210 | Standard bearing designation indicating a 50 mm bore and 90 mm outside diameter. |
| E | Optimized internal design for increased load capacity. |
| TN9 | Nylon cage, polymer material, suitable for high speeds and offering good wear resistance. |
| W64 | Specification for a special lubricant, providing effective lubrication within the specified temperature range. |
1210 ETN9/W64 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball construction provides superior high rigidity, enabling stable support for shafts under heavy combined loads. This design effectively handles significant radial forces and moderate axial loads from both directions.
High-Speed Performance: The lightweight Nylon (TN9) cage minimizes centrifugal forces and friction, contributing to the bearing's capability as a high-speed bearing with a limiting speed of 10,000 rpm. The pre-applied W64 lubricant ensures optimal performance across the operating temperature range.
Precision & Durability: Manufactured from Chrome Steel for both rings and balls, this bearing offers high durability and resistance to wear. The standard CN radial internal clearance is suited for most common applications requiring precision operation.
1210 ETN9/W64 Bearing Typical Application Areas
The 1210 ETN9/W64 is ideally suited for a wide range of industrial machinery and equipment, including:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Equipment
- Precision Agricultural Machinery
