Product Description
The ZARN70130-L-TV INA Needle Roller/Axial Cylindrical Roller Bearing is a high-performance combined bearing designed for complex load-bearing applications requiring simultaneous radial and axial load support.
Product Construction
This precision-engineered bearing comprises:
- Outer ring with integrated radial and axial raceways
- Extended and stepped shaft locating washers (L-type design)
- Inner ring
- Radial needle roller and cage assembly
- Axial cylindrical roller and cage assemblies
Key Technical Specifications
- Inside Diameter: 70mm
- Outside Diameter: 130mm
- Width: 103mm
- Configuration: Double direction load capacity
Special Design Features
The L-type variant offers unique advantages:
- Extended and stepped shaft locating washer
- Ideal for applications with limited axial shaft support
- Suitable for bearings that cannot be sealed on the standard shaft locating washer due to space constraints
Typical Applications
- Machine tool spindles with complex load requirements
- Automotive transmission systems
- Precision positioning equipment
- Robotics and automation machinery
- Industrial gearboxes requiring advanced load management
- Mechanical systems with restricted mounting space
The innovative design allows for efficient load distribution, making it an optimal solution for demanding industrial applications where both radial and axial loads need to be managed simultaneously.
