| Model Segment | Technical Meaning |
|---|---|
| QJ | Denotes the Four Point Contact ball bearing series. |
| 1096 | Specifies the bearing dimensions: 480mm bore, 700mm outside diameter, 100mm width. |
| N2 | Indicates special internal design and brass cage material. |
| MA | Signifies that the bearing is lubricated and ready for operation. |
QJ 1096 N2MA Bearing Structural Features & Performance Benefits
The QJ 1096 N2MA incorporates several key structural features that deliver superior performance:
- Four Point Contact Design: Enables the bearing to handle significant combined loads (radial and bidirectional axial) in a compact, single-row configuration, providing high load capacity and system rigidity.
- High-Precision Components: Manufactured from Chrome Steel for rings and balls, ensuring durability and resistance to deformation under the high static load rating of 630,000 lbf and dynamic load rating of 238,500 lbf.
- Optimized Cage and Lubrication: The brass cage provides stability at the limiting speed of 1,300 rpm, while the pre-applied lubrication ensures immediate readiness and smooth operation within a temperature range of -30°C to 110°C.
- Precision Ground: The P6 tolerance class guarantees tight dimensional control for precise shaft positioning and reduced vibration in high-accuracy applications.
QJ 1096 N2MA Bearing Typical Application Areas
The QJ 1096 N2MA is suited for heavy-duty machinery and precision equipment, including:
- Industrial Gearboxes and large power transmission systems.
- Heavy-Duty Turntables and slewing rings in construction and mining equipment.
- Large Pumps and Compressors requiring robust support for combined loads.
- Wind Turbine Main Shafts and other renewable energy applications.
- Precision Machine Tools and indexing tables where high rigidity and accuracy are critical.
